To avoid misunderstanding, I believe there should be an open communication line throughout the process. Also, it would be conducive for everyone in the team to write their code clearly and in an organized manner. This way, it would be easier for the other members to pick up where the previous member ended their tasks.

It rarely happens, but sometimes, there are projects that I could not meet certain deadlines. Most of it occurs when unforeseen problems come up. That’s why I strongly believe that proper planning and documentation are very important.
