No project goes to the wrong development unless you are paying improper attention towards it. There are few elements which needed more attention to develop the right system.
More concentration on budget and project deadline rather than planning and stakeholder demands:
Focusing on project completion without even start making the project can cause too much pressure on employees which leads to bad results. Poor communication with the stakeholders during development drives the project far away from what the customer actually wanted. It becomes more expensive to change the initial plan and architecture and it is almost impossible to reach the customer goal.
Negligence in building effective teams:
Communication and motivation are very essential in every development team. Inadequate understanding among the project group members affects the development and conflicts may slow down work results delay in completion of the project on time. Identifying and removing ineffective people like bad developers or people lacking motivation before they may change other group members is one of the essential elements.
Inadequate stakeholder communication:
Satisfying the initial requirements isn’t enough. The project must be able to work for the future amendments. Without frequent communication with stakeholder during development is hard to achieve. Due to the improper communication, collecting not enough data on objectives leads to same negative results.
Improper unit testing and QA session:
Some reasons like whenever deadline approaches or the budget is over, there is tendency to skip or pay less attention towards testing. Even if the project just works correctly based on presumptions, it isn’t the successful project. Apart from customer requirements, it has to satisfy some factors like quality (tolerate longer delivery cycles) and platform independency (must work on every hardware).
