This case is based on a situation where the client spent a lot of time and money working with an unprofessional team that was not able to understand requirements and built an incomplete and low-quality solution. The client relied on them for about 1 year but when the project budget was almost over and the product was still not working, the client decided to find another firm to finalize it. This firm was Jappware.
