Task division among different teams: This best practice says that it is better to distribute the activities of the different steps of the development life cycle among different people. This will reduce the burden on one person and achieve better results in less time. It is better to choose one team (maybe one to two members per team) for each of the design, implementation, and testing phases. These teams will work in collaboration with each other, as they have their respective responsibilities to be performed at different times. This is always better than different teams collaborating with each other. This collaboration is depicted in the following figure with common shape in different steps. The designers may support the developer team in programming, and this approach can be considered as pair programming. Similarly, the collaboration of an implementation...
