Google introduced AngularJS as an open-source framework specifically to address the challenges faced by the mobile app developer in creating and testing code. So, how does it do that?

AngularJS integrates HTML code along with the application modules.This forms an innovative framework that is now widely used to restructure JavaScript code. AngularJS is designed to help accumulate data by adding and eliminating extra source code to maintain the overall code integrity.

What is AngularJS?

In 2009, Google launched AngularJS, and it turned out to be a great framework for building iPhone and Android mobile apps. It doesn’t offer many add-ons but there are an array of features which makes it a perfect fit for the mobile app developer’s toolbox.

Its interactive abilities with backend, web servers and external data sources help mobile app developers build a feature-rich mobile app easily, quickly, and flawlessly.

A key value is that AngularJS helps to manipulate jQuery Document Object Model libraries. Another great feature of AngularJS is that it enables developers to expand the functionality of HTML by adding constructs through its two-way data binding. With its directives, mobile app developers can accumulate data into HMTL and can abstract DOM modifications.

A Summary of AngularJS:

AngularJS can be easily added to an HTML page through a simple coding script. The modular approach helps the mobile app developers segment codes, simplify testing, and update maintenance activities on different types of mobile apps. It has a few manipulations of JS and HTML, which adhere to the fundamentals, thus helping to deliver better stability.

It extends HTML templates, enabling an advanced approach in managing and editing the components. Mobile app development with AngularJS is extremely efficient, bug-free, and scalable.

Now that we are familiar with the basics of AngularJS; let’s explore how AngularJS can be very helpful in creating the best mobile apps with rich functionalities.

Build Mobile Apps with Advanced Development Practices:

Nowadays, every app is data-driven, and it makes obvious sense to use a tool that is built to address just this scenario. Simplifying the following three advanced software practices has made AngularJS the ideal choice here.

1. Three-way Data Binding:

Data binding has become a crucial aspect of mobile app development. When the data model updates, the UI (User Interface) must also change and update. And when app UIs updates, the mobile app developer updates the mobile to match with application’s UI. This is called two-way data binding. AngularJS takes that a step further.

Three-way data binding is an idea that the developers can not only keep the UI but can also sync the data with the backend services. This means the developers can take inputs from an app, process it, save it on the webserver, and keep the UI in sync. With jQuery iOS and Android Background, the developers find AngularJS’s three-way data binding a considerable time-saver for app development.

2. Reusable Codes:

It helps developers keep the UI, data, and code logic discrete. That means that AngularJS enables them to reuse older code on different devices and also on different platforms. It also allows the developers to customize their UI for each platform to provide a better user experience. In the past, application development was only limited to the PC and desktop.

But now, there are mobile devices with different operating systems, different functions, and different UIs. Thus, developers now have to create code for all the platforms separately. They cannot reuse that code. AngularJS addresses this issue by enabling the developers to reuse code which has been previously created.

3. Testability:

When it comes to end-to-end unit testing, AngularJS provide advanced support. It offers flexibility to the developers so that they can conduct testing more efficiently. It has impressive testing compatibilities like the dependency injection concept to reuse, maintain, and test the code. In dependency injection, the components are given specific dependencies.
This helps to locate the code and makes it configurable. Thus, the quality analyst can quickly check the code and its dependencies and find bugs easily.

More Reasons to Use AngularJS:

Apart from three-way data binding, code reusability, and easy testing, there are other benefits that developers can experience while working with AngularJS.

• Easy to understand: The code written in AngularJS is not only easy to understand but also easy to maintain and test.
• Customization: While writing code, the mobile app developers do not require to add all the libraries at the same time while adding other modifications.
• Wider Community: The Google community supports AngularJS which means the developers will get wider support to fix any issue.
• Pre-defined Solutions: AngularJS comes with a pre-defined and versatile solution which can be used within the app. Developers can get pre-defined UI routing approaches and module practices to help them get their app created sooner.

Most Successful AngularJS Domains:

Businesses are looking to stand apart from the competition by creating impressive AngularJS mobile apps. Many tech-giants have significantly invested in AngularJS to provide a high-quality user interface and user experience. YouTube, Netflix, Upwork, and PayPal are some of the examples of mobile apps working on AngularJS. Developers looking to create mobile apps with great user experience are using AngularJS in domains like.

• On-demand video streaming apps.
• Travel and destination finder apps.
• Weather updates apps.
• User-generated and content portals.
• Apps for user reviews.
• Interactive social apps.

Clearly, AngularJS provides many benefits when it comes to creating seamless mobile apps. It is a futuristic framework which will continue to redefine the way mobile apps are developed. Does your mobile app strategy include AngularJS?

Can you imagine the possibilities of downloading HD movies on your phone in seconds rather than hours or minutes? What about immersive games that blur the lines between reality and alternate reality? Both the scenarios may become commonplace in the future with the coming of the next-gen cellular technology – 5G.

As is apparent, 5G is generating a lot of interest in the mobile industry. With consumer interest high, many firms are thinking of making apps that can leverage the latest tech. The relatively new tech remains a concept for the wider world, but it clearly has the potential to deliver a massive impact. The technology could also drive big changes in mobile app development.

In no particular order, the considerations we will have to factor into the new 5G-capable apps we develop will include:

• Exponentially High Data Speeds – 5G networks can achieve significantly faster data speeds of up to 10 Gbps. This is a stark contrast to the 1 Gbps speed offered by its predecessor 4G. That will allow for the transfer of much much higher volumes of data.
• Low to Zero Latency – Latency is the time taken by a device to send a packet of data to a different device. On current mobile networks, this is about 50 milliseconds. With 5G, this will be reduced to about 1 millisecond. Surely, this will pave the way for several AR and VR based apps in particular.
• Better Connection Density – IoT is going to grow over the next few years. To accommodate billions of devices that are a part of IoT, there is a need for a network that offers better connection density. 5G will be able to support the connectivity of up to 1 million devices in a span of several miles. Watch out for the new IoT-everywhere world. And for the mobile apps that will inevitably follow.
• Precision – 5G has better precision capabilities and it will be useful for creating high-precision mobile apps, such as the ones that are GPS-enabled. Looks like location-based services may become much more common.
• Lower Battery Consumption – Features such as reduced latency and increased speed translates to lower battery consumption. In fact, 5G will be able to extend the battery life of both IoT and mobile devices up to 10 times! This is great news for both app users and developers!
• Opens Up New Avenues – HD content, 360-degree videos, holographic videos, multi-person video calls will all become a breeze on 5G networks. This will help developers create a variety of apps that cater to the users’ interests.

How 5G Will Change Mobile App Development?

We have seen a picture of the future of 5G and how it is going to shape mobile app development. Here is what is 5G mobile app developers need to think about:

1. They Can Develop Apps with Rapid File Transfers – Several apps, especially productivity apps require the users to exchange files, data, and other forms of information. 5G with low latency and high speed will be a boon for such apps and offer the users speedy transfer. Think how smoothly your apps will run without any lag! This also means that users will be highly satisfied with the overall experience and won’t abandon the app/uninstall it from their device.
2. Media-Rich UX – 5G will be able to provide rich UX like never before. From watching movies to listening to music, or playing a high-quality game, the user experience will be uber-intense on the new network. This means that developers can give free rein to their imagination when it comes to the UI and take it to the next level.
3. Better Capacities and Features – For IoT, AR/VR, and other apps that use new technologies, developers will be able to build feature-rich apps that have exceptional user experiences. Powerful apps with outstanding user experiences will drive new monetization possibilities and increase app revenues as well.
4. More Navigational Apps – 5G will be useful for creating GPS-enabled apps, which means that there will be more navigational apps in the future. The network will offer high-quality and uninterrupted communication, which is going to be a boon for such apps that are useful for the travel and tourism genre of apps as well as for utility apps or apps for wearables.
5. Swift Feedback – Chatbots and voice bots powered by 5G networks will be able to provide instant feedback and offer better, real-time experiences to the users. No more wait times mean better conversations. This promises many use-cases like specialized apps for the customer care sector.
6. Low Dependence on Hardware – The enhanced communication speed and delivery speed of 5G network also mean that the mobile apps of the future will be less dependent on device hardware. Therefore, it may well pave the way for device-agnostic apps.

The Road Ahead

While the coming of the 5G network will bring forth a plethora of opportunity for mobile apps, the path forward will be challenging. 5G, like any technology, will come with its own set of challenges. Evolving standards, security loopholes, setup of new business models, and the creation of the necessary infrastructure are some of the core issues at the nascent stage of adoption. This is why, even though the technology will be a game-changer, mobile-app developers need to tread carefully.

That said, there are opportunities aplenty to leverage 5G’s capabilities to design and deliver cutting-edge apps even in the early days of 5G implementation. It’s time to break out of the rut of slow, high-latency, low-capacity networks and embrace the promise of 5G!

Even before the Agile methodology became commonplace in software development, the Rapid Application Development model brought flexibility to the entire development process. Rapid Application Development quickly swept the Waterfall model out of its place. And it continues to deliver value.

Rapid Application Development helps to quickly develop prototypes to test functions and features without having to worry too much about their impact on the end product. With RAD, you can add or remove functionalities, change the design of a software product and clean it up by eliminating extra fluff – all without harming the end product.

Markets and Markets have predicted the Rapid Application Development market will grow from USD 7.8 bn in 2018 to USD 46.2 bn by 2023. This growth is driven by the ever-rising demand for faster software programming with low-code, and customizable and scalable solutions.

But how did the RAD model come to light? Is it the right model for your software development process? When should you choose to work with Rapid Application Development?

Let’s find out.

Rapid Application Development in a Nutshell

The Rapid Application Development model prioritizes quick prototyping instead of long, drawn-out development and testing cycles. With Rapid Application Development, developers can make multiple iterations to their software without having to start from scratch each time.

Rapid Application Development has been around since the 1980s. So it’s not new but has always found value in projects where the continuous evaluation of development is at the core.

Steps Involved in RAD

Although RAD has massively evolved over the years, these four basic steps remain at its heart.

• Define the Requirements– The Rapid Application Development model does not need you to start with a detailed list of specifications. Instead, it encourages developers to ask for requirements at the time. As the project advances deeper into the development cycle, the specifics of the requirement can be further ironed out. This step sets the stage for the ultimate success of the project. This is where the developers, users, stakeholders, and other members sit down to discuss the goals and expectations of the project. They also address the current and potential challenges that may hinder their path during development. The key to successful RAD is for all the stakeholders and users to be involved right from the beginning to define the goals and expectations.
• Build the Prototype – Once the scope of the project is clearly chalked out, it’s time for the developers to dive in. In this step, the basic user design is built through prototype iterations. During this phase, users or clients collaborate with developers to make sure their requirements are met at every step in the design process. The developer designs a prototype, the user tests it and provides feedback on how it can be improved. Ultimately, through this collaboration, there is less chance that something will slip through the cracks.
• Rapid Construction – The prototypes and beta systems developed in the previous stage are now converted into working models. Since a large number of glitches and gaps would have been addressed during the prototyping process, the developers can now move at full speed in constructing the product. It is fascinating that even during this phase, the end users provide inputs, and suggest modifications which are subsequently accommodated.

The last two steps repeat iteratively until the client’s objectives and expectations are met.

• Finalizing and deployment – In this step, the features, user experience, and interface of the software are finalized with the product owner or client. Before delivering or deploying the product at the client side, developers test the software for stability usability and maintainability.

RAD- When And Why You Stand to Gain

Does it make sense to use the Rapid Application Development model for each type of software development? Perhaps not. Here’s when you can use Rapid Application Development-

When you have access to a pool of users

If you have got users who can give consistent and reliable feedback on your prototypes, the Rapid Application Development is a great model. Since the RAD model has its roots in the feedback developers receive throughout the cycle, is not the best model without access to dependable sources who will use and review your product in an unbiased manner.

When you Need Quick Delivery:

If you are on a tight deadline, RAD could help. You can cut down on the requirement planning and design phases which individually consume time, and begin prototyping rapidly to deliver something that works sooner. Rapid Application Development is an on-the-fly approach that leads to quick development. Some estimates are that the RAD approach can slash the traditional technology lifecycle by 80 percent.

Rapid Application Development-

• Is a flexible model that can adapt to changes.
• Minimizes the overall project risk.
• Is easy to transfer deliverables in the form of high-level abstractions scripts and intermediate codes.
• Allows Iterative prototyping that reduces the possibility of bugs and defects.

Clearly, with RAD, an organization can build a software product faster, eliminating the need for long development lifecycles and hassle-filled development journeys. Does that sound like something you would consider for your next software development project?

We all know the history of the MVP. The concept of MVP, an offshoot of the Lean Startups movement, was popularized by Eric Ries-a consultant and writer on startups. The minimum viable product (MVP) is a development method in which a new product is developed with just enough features to satisfy the initial adopters. The final, comprehensive set of features is only planned and developed after analyzing feedback from the product’s early users. This feedback is gathered often, and product versions are released often.

In its essence, a minimum viable product is the most trimmed down version of a product that is still suitable for release. In simple words, the MVP has sufficient value for people to adopt or buy it initially. A key characteristic is that it displays promising future benefits to retain initial adopters. A vital component of the plan is that it renders a feedback loop to support future development.

An obvious drawback or rather difficulty with this development methodology is that it assumes that the initial adopters can visualize the outlook of the final product and give the required feedback to help developers progress.

Have you wondered, why the concept of an MVP was introduced in the first place? Well, because in a startup environment, mistakes are the norm. In fact, studies show that nine out of ten startups fail. To get around this failure rate, many startups began to build a Minimum Viable Product. The aim was to embrace the fact that they would fail but to fail fast and fail often so that they still had resources to recover.

However, Several Startups are facing failure despite going the MVP route. Why?

This happens because when companies expose an MVP to a test audience, they often get distracted. They lose sight of the end objective. Sometimes, the immediacy of the task of making the next release successful draws them away from the larger objective of pursuing a more significant market segment. The big picture may call for them to change direction or to design an unusual feature. This could lead to cost-intensive rework, loss of focus, and, in turn, a failed product.

To Avoid Failure and Make the Most of Your Minimum Viable Product, Here are a Few Mistakes to Avoid While Building an MVP.

1. Targeting the Masses:

You cannot begin your development with the mindset that your product is something that everyone needs. You must design your product in a way that it focuses on a narrow market segment that will benefit the most from using your product immediately. If you try to create a one-size-fits-all type of product, you will not be able to do anything competently.

Facebook is a perfect example of an organization avoiding this trap. While yes, today, Facebook is a platform that everyone uses; they didn’t start this way. Their initial focus was on college students. By customizing their product for a narrow segment, Facebook managed to build a better and more focused platform. This enabled them to expand later.

2. Overtaxing the Initial Users:

While seeking feedback, too often, companies make the mistake of asking too many questions and over-taxing the users. However, on the flipside, even a deficit of information from the users is a drawback. Companies are often stuck in the limbo of asking too few questions to ensure maximum participation but end up getting the feedback they can’t use because it is not specific or actionable enough. Therefore, it is essential to make the testing process as user-friendly as possible and create user surveys that ask detailed yet relevant questions.

3. Choosing the Wrong Features:

The primary purpose of an MVP is to test the idea before proceeding to complete development. An ideal MVP has only a few core functionalities that offer the end-users an understanding of the product and the issues it resolves. The selection of features is a crucial process in the development of an MVP. Too many companies spend a significant amount of time and budget in polishing the design and adding more and more features to impress the audience.

The downside of this is that after spending the most vital part of a project budget on building an over-designed MVP the product idea may be rejected by the audience. On the other end of the spectrum, some companies adopt the ultra-minimalist approach and ignore the viability aspect of the product. Since their focus is on reducing a set of features, they overlook the elements that make their product unique and useful for users. The product fails to find favor with the users because it will not deliver sufficient meaningful value.

Lastly, it is important to keep in mind that MVPs tend to get enormous amounts of data and ideas from customers.  Much of that data may suggest changes that may not be suitable. While yes, these ideas and suggestions are great to broaden your horizon, it may be wiser to avoid making significant adjustments immediately. If you expand too quickly you may not be able to gauge which features are creating a positive impact and which are stirring a negative response.

Do remember, there will be plenty of time to progress into new directions once you are confident that your product is well-designed and that it meets the needs of your core clientele.

The uber-significance of software in the business world has given rise to an extraordinary windfall of software development methodologies. It’s also true that the software methodology you choose can make or break your business. The wrong choice can result in miscommunication, schedule and cost slippage, wasted time, and resource burnout. So, how to choose?

Factors to Consider while Choosing the Right Software Development Methodology

Choosing the right software development methodology among many alternatives could be challenging. Yet, this choice is crucial for it will decide the fate of your project. For teams having a hard time choosing, here are the top factors to consider:

• Size of project: The size of the project is one of the first aspects to keep in mind while choosing a development methodology. While small projects with limited requirements will only need a handful of resources for successful delivery, large projects that span software generations would require many architects, developers, and testers spread across locations.The size and scale of the project determine the project management plan and the number of developers needed to handle it. You must choose a methodology that allows for constant collaboration and feedback between the teams so the end product meets the intended requirements, and is delivered within time and budget.

• Fluctuations in requirement: With customer demands and market dynamics constantly changing, changes must be made to the software to drive better experiences. Dynamic requirements also determine the methodology you choose.
  If stability and predictability are the norm and ongoing changes minimal, traditional methodologies work well. However, if you need to constantly incorporate new features and enhancements in your code, you need to choose a more modern methodology that allows for such changes to be embedded – without impacting cost or schedule.

• Cost of delays: Staying on schedule is important for any software development project. Yet, with requirements constantly changing, software projects invariably overshoot deadlines. Obviously, this substantially impacts costs too.
  The larger the scale the more the pressure to deliver on time. If not, the project risks massive cost of delays. For smaller projects,the impact of a schedule overrun is not so drastic. Make sure to choose a methodology factoring in how delays impact the project and your organization.

• Team locations: The software methodology you choose must also depend on how dispersed your team is.
  If your developers, engineers, and testers are located across different geographies, miscommunication, confusion, and missteps may become more common in the development process. That suggests a greater need for coordination, coherence, and accountability. A transparent and collaborative project management regimen is needed. Then teams can stay updated about the progress of the project, and work together towards common goals.

• Feedback frequency: In a customer-driven world, there is a constant clamour for new features. Some projects require customer feedback to be constantly incorporated. While some projects may require more such feedback elements to be baked in due to the complexity and the size of the project, some require far less. The software development methodology you choose will depend on how frequently you have to incorporate customer feedback.

The Options at Hand:

A variety of factors come together to have a considerable bearing on the project. No matter the type of software you are building –choosing the right software development methodology is critical to ensure happy teams, on-time delivery, and easily-met business and end-user needs.

Here are the options you have at hand:

• Even today, if your requirements are clear and fixed, the best-suited development methodology is Waterfall. Offering a well-defined phased approach to software development, the waterfall methodology allows you to design the solution as visualized. Since there will be no surprises or changes in the requirements along the course of development, you can seamlessly proceed with development, integration, and testing based on the design, and deliver the product on time.
• If your requirements are fairly straightforward, but you do not have a clear picture of how the solution should be built, you will need to choose a methodology that enables constant feedback. Kanban allows you to constantly monitor the product, check on tasks in progress, prioritize them if needed, and receive feedback on a continuous basis. Such feedback ensures the software you are developing is in line with the intended need and as visualized at the beginning.
• If your requirements change frequently, the Agile methodology will allow you to meet your goals better than others. Using Agile, you can build projects in sprints and accommodate a fair number of changes and enhancements – with less cost of delay. Since each sprint needs to be completed in a given time frame, you can ensure you stick to the commitment and complete all tasks within the sprint – in time and within budget.
• If your requirements change frequently, your teams are dispersed across the globe, and the cost of delay is high, DevOps can help you drive rapid software delivery. This is especially beneficial in case of products that live on the Cloud -like SaaS products. By fueling better communication and collaboration between the development and operations teams, DevOps helps to condense development cycles, increase deployment frequency, and meet software needs quickly and efficiently. It helps reduce development complexity, detect and resolve issues faster, and allows you to deliver high-quality, innovative software.

Always look at the Bigger Picture:

It is crucial to make the right decisions about tools, resources, schedule, and budget in software development. Do consider aspects such as the size of the project, fluctuations in the requirement, cost of delays, team location as well as the feedback frequency and then make the choice of development approach.

The right software development methodology will allow you to deliver quality outcomes in the time and budget allotted. When looking for the best software development methodology, ensure you consider the bigger picture. This choice will give you the best results for the effort, money, and time invested. How did you zero in on your product development approach?

   Gartner estimates that the revenue from the AI industry will touch $1.2 trillion by the end of 2019. By 2022 the business value derived from AI is expected to reach $3.9 trillion. With the digital transformation wave taking over almost all organizations, it is clear that AI will continue to trend in the software universe for the next couple of years.

   In 2019 we will see the use of AI to speed up and improve the accuracy of software development- be it in automatic debugging, for creating intelligent assistants to speed up development processes, to automate code generation, or to create and train an automated system to produce accurate estimates to develop MVPs faster…the AI impact will be all around and hard to ignore.

2. Blockchain:

   Blockchain, the meta-technology, holds the promise of completely reshaping software development. Blockchain consists of a single ledger of transactions and enables smart contracts. It has a distributed database that is accessible to a peer-to-peer network but is protected against unauthorized access. The technology is secured by cryptographic technique making the applications developed using this tech more secure.

   Blockchain has already made its presence felt in several different sectors be it retail, banking, financial services, healthcare, and public administration. It is only a matter of time before Blockchain becomes a prime focus for organizations involved in software development. As security becomes top of the mind, the need for blockchain-based applications will increase. 2019 looks like a good year to jump on this technology trend.

3. Progressive Web Apps:

   Progressive Web Apps leaped to our attention when Gartner announced it as a software trend in 2017. In 2019 however, with a more mature app ecosystem in place, we expect to see Progressive Web apps become more dominant and gain that promised place. As the app economy gets stronger and the mobile environment evolves, progressive web apps are gradually going to become the new normal in this changing environment.
   Research shows that progressive web apps show a 68% increase in mobile traffic and are 15 times faster to load and install as compared to native apps. Progressive web apps also require 25 times less device storage space in comparison to native apps. These applications are also less complex to develop, are easy to maintain and provide the benefits of mobile experience with the features of browser technology. What’s not to love?

4. Security Rules:

   Security has been on everyone’s mind in the software development space. The increased focus of security during software development is only going to increase in this year. Research from Alert Logic showed that data loss and leakage is one of the biggest concerns for cybersecurity professionals (67%). Threats to data privacy were the concern for 61% while 53% were concerned with breach of confidentiality.

   Owing to the huge impact security issues can have on a software product and its users, organizations are conscious of baking security into the process of software development. Software development companies also have to keep a close eye on regulatory considerations for specific industries.

   They must also follow security best practices and ensure that all security guidelines and protocols are met consistently. To make security more robust, organizations are also looking at Managed Security Providers or MSP’s for robust application security without compromising on development timelines.

5. Automated Testing:

   While test automation has been around for a while, automated testing will continue to be a trend in 2019. This will continue for as long as there is a need to release better-tested products into the market faster -that means, forever! As testing gets deeply ingrained into every software development methodology, test automation will get even more pervasive with testing teams striving for greater levels of automated test coverage.

   In 2019 we will witness test automation leveraging AI for better test accuracy. Tests will become more comprehensive, more intelligent, and more dependable. Even with that, that they will become faster and less taxing. The products will become better tested and more robust as a result.

   Borrowing from, and evolving the technologies that help to automate testing, Robotic Process Automation or RPA will also become a dominating trend in 2019. RPA will drive to automate high-volume repeatable tasks, thus making them faster, more accurate, and less effort-intensive.

Conclusion:

2019 promises to be an exciting year in the world of software development. It will be interesting to see how these trends develop over the course of the year. Check back with us at the end of the year for a review of our predictions. And, do feel free to add more about the trends you think will dominate software development and testing in 2019.
