What problems can arise if the client, developer, and user are the same person? How can these problems be solved?

1 - if all three are the same person then possibility of verifying the software or its scope for the general public will remain unknown

2 - it will not return any profit when all are the same person thus it will remain in one isolated environment

3 - it cannot be used by the masses if all three people are the same person

Explanation:

while building any software system it needs three sets of people who are an important part of this development chain. They are the client, developer, and user. if suppose all three are the same person while developing any software then some problems are occurring and that are mentioned below

1 - if all three are the same person then possibility of verifying the software or its scope for the general public will remain unknown

2 - it will not return any profit when all are the same person thus it will remain in one isolated environment

3 - it cannot be used by the masses if all three people are the same person

the one thing that needs to be done for removing all these problems is to assigned different people for different phases. so that the developer can validate the scope of software in the market.
