Developing any app not just a chat app requires a detailed analysis of the customer requirements and their target audience expectations. This requirement is further carried with the feature finalization for fulfilling that requirements.
Developing a chat app requires experts in the following subjects as they will work in coordination to create a high performing chat app
· UI/UX Designer
· Structure/Framework Designer
· Front End Developer
· Graphic Designer
· Backend Developers
· Quality Analyst
· Project Manager
Depending on the work to be carried by each team the number of members will vary. Also for some of the activities, a single member can be an expert in 2 subjects so that reduces the overall team strength sometimes.
The work carried out by each team and the launch deadline will help in deciding the total tea members. Being a developer with 7 years of experience I can suggest an approximate team size of 6-12 members for a launch date of 3-6 months.
So based on the customer & User Requirements a development team will analyze complete requirements and then carry out research on the time it takes to develop each feature. once the time of development is calculated after adding some contingency allowance it is multiplied by per hour development rates to get the final development cost.
Now depending on the time, it takes to develop and the day you have before the scheduled launch the number of team members can be varied.
Hope that clears your doubt on how much time or how many developers it requires to develop a chat app
