1) Create a plan on how you would want to build the app
First, come up with a written definition of the app you're planning to create. Determine who your users are and how they're going to take advantage of the app. You can also explain here the unique issues that the app can resolve or the transactions that it can simplify for customers.
Second, you can also check if there's already an existing app that's similar to the one you're planning to build. If so, think about how you can make it look or work better.
2) Brainstorm ideas with the technical team to visually define concepts
This is the best time to get the technical team involved as they can help determine if your idea is realistic or feasible. They can also help set your expectations on the success rate, the time required to finish the project, budget, and a lot more. Moreover, this is where you can sketch your ideas to the technical team.
3) Assess the feasibility of the functionalities of the app
Determine where your app can be used. Depending on its platform or format, the app may have different requirements. This means that programming may be different for an app that's to be used on an Android device to that of an iPhone or iPad.
If there may be a functionality that is deemed not feasible, then this is the best time to correct them.
4) Experience the app and observe how it works
By building a rapid prototype, a client may get to experience as quickly as possible how an app looks and works like. This is necessary for the technical team to quickly address any feedbacks from the client.
5) Design the app and make the necessary preparations for development
This stage is where the real work starts. Before the technical team starts coding, the user experience (UX) designer will create the design elements' interaction architecture. Meanwhile, the user interface (UI) designer for mobile solutions will come up with the look and feel of the app.
6) Create your mobile app using agile methods
By this time, you already have a clear app design. Therefore, you should now be ready to build an app. Here, agile development is a better approach due to the importance of rapid iteration to adapt to change, transparency, and collaboration.
7) Test how your mobile app works
Alright! You've finally built your app. It's about time for target users to help you check how the app works. If your app passes the user acceptance test, then you can be sure that the solution brought by the app really works.
Before you even think of launching the app, you can also make it available first for a beta trial. That way, you can again address any issues raised by the users.
8) Launch the app
If the beta trial goes smoothly, you can launch the app and enjoy the fruits of your hardwork. This doesn't mean though that your job ends here. Remember, you need to keep up with the changes of the current time. Make sure to update your app regularly.
