Final answer:
In project planning, the desirable planning sequence depends on the project. Each project is unique and requires a specific planning sequence tailored to its requirements and objectives. Project plans may need to be adjusted as circumstances change or new information arises.
Step-by-step explanation:
In the process of project planning, the statement that is true is that the desirable planning sequence depends on the project. There is no one-size-fits-all approach to project planning. Each project is unique and requires a specific planning sequence tailored to its requirements and objectives.
For example, in new product design projects, the development of a detailed design from a design concept may take up most of the time allocated. A poor detailed design can have a significant impact on the success of the project, even if the initial design concept was good.
It is important to note that project plans may need to be adjusted as circumstances change or new information arises. It is not always possible or advisable to keep the remaining parts of the plan unchanged if one part changes.
