First, App design.
To make a product, we must first have a good idea. Be sure to find out who is the user of this APP (market positioning), what kind of problems have been solved for users (core values), how to solve them (product functions), whether there are substitutes (competitive analysis), what benefits have been brought to the owners of the APP (business model), and how to get the target users to contact, install and use this APP (promotion and marketing). . . .
Second, user experience.
To come up with a solution, what are the user's usage scenarios, attitudes, core functions, health care functions and marginal functions, how to establish the best operation path, how to allocate functions on the page, and what style and style the interface should be. . . . Finally, draw the UI scheme.
Third, programmers.
Programmers to develop, to test, may be interested in this piece, then talk more. What abilities should an iOS programmer have?
1, language basis: Objective-C language, xcode development environment; 2, mobile phone experience: enough iPhone experience and experience, otherwise it is difficult for you to communicate effectively with product managers and designers; 3. Specific development capability: the main development will focus on interface development, certain database development, communication interface development, collaborative development and joint debugging. If it is a game, it also needs to involve engines, modeling, materials, light and shadow, storyboards and so on.
If you are an independent developer, you should have the above three roles. This is not the product operation after development, but don't worry, things always get easier after you actually work hard.
