It’s a very important phase because it allows to unblur all aspects of the future app and to clarify further ways of development.
We’ll go from start to finish and briefly describe all steps of this phase.
This phase is very important to determine all app features and business goals, target audience, and much more. Usually, you’ll discuss these aspects with a Business Analyst and this employee may set a determined schedule of calls to gather as much information from you as possible. This step is vital because all further steps rely on it.
After you tell a full feature list, the Business Analyst will make a specification. It’s detailed documentation with all app features, technologies, and their dependencies from each other. This documentation greatly simplifies communication between business and developers. The specification is always getting approved by the app owner. The specification is usually split into smaller parts to make it easier for you to review it. It can be a part of functionality or one big feature.
Wireframes are schematic blueprints of app screens showing the links between all screens and their layouts.
When specification and wireframes are done, they pass the approval process by the QA engineer. They check it for logical mistakes or guidelines violations.
When all crucial steps are passed it’s possible to make a detailed estimate that includes full development price and total hours of development. From now on the company knows how to create an app for iPhone based on your goals and needs. If estimated numbers fit your resources, the team moves to development.
