Good plans help save time in various manners. Good plans try to build a road map of all tasks that will be required to develop the database and what functionalities will be added in each step. Thus, the database developers know exactly what to build. This leads to minimal waste of time as well as rework during the development process because developers don’t have to guess which functions should be added and they don’t have to send prototype to the customer again and again to make sure they are on the right track.
Good plans also try to estimate all the resources that will be needed as well as approximate time durations that each task will take. Moreover, the database can be built faster by dividing the tasks among different teams instead of only one team building the whole database. Because the plan shows how each part will interact with the other parts to form a complete database, different teams working on the database will know their responsibilities and there will be no overlap between them.

The client will also know exactly what the developers need and when so that they can arrange funds and other resources accordingly. Since good plans include detailed roadmap of the database development, they can also be used to test the quality of the database once it has been finished. Because the good plans allow developers to build databases exactly to the needs of the users as well as carry out a comprehensive testing of the final version, fewer problems will arise later, resulting in less downtimes and lower repair costs.
