It emphasizes rapid prototyping and the creation of a minimum viable product: this is then rapidly iterated to add features and functionality and address any issues. Rapid application development was created to address some of the problems of waterfall development. But it also requires large teams and is slow: long lead times mean that business requirements or the competitive environment might have completely changed by the time the application is launched. It is meticulous: a lot of work goes into defining and scoping projects requirements, and a project manager oversees the entire process. The waterfall approach has pros and cons. Traditionally, all organizations deployed the waterfall approach where teams would define everything at the start of a project, then build it, then give it to customers. The next challenge is to decide what application development methodologies you should use. Main Application Development Methodologies To learn more about when you should build versus when you should buy software, take a look at the blog post Build vs. However, US Labor statistics suggest the tech talent shortage amounts to 40 million skilled workers globally, so software engineers are a scarce and expensive resource. On the other hand, if an organization has unique requirements (or uses digital technology to generate business advantage), creating in-house software is a better bet. Many off-the-shelf applications provide all (or, at least most) of the functionality needed to implement all the business processes you might wish to support. After launch, it's important to monitor user feedback, identify areas of improvement, and release regular updates to fix bugs, introduce new features, and enhance the app's performance and security. Maintenance and updates: app development is an ongoing process. ![]() The app is then submitted to the respective app store for review and approval. App deployment involves preparing the necessary files, certificates, and app store guidelines compliance (e.g., Apple App Store or Google Play Store).
