The systems engineering method applies to the advanced development phase in a similar set of four steps, as it does to the preceding concept definition phase. For each step in the method, compare the activities in the two phases with one another, stating in your own words (a) how they are similar and (b) how they are different.

The specification of the product requires market specifications, customer requirements, receiving goods and services, operating requirements, system eligibility criteria.
The paper, and on the other hand, explains the sub-systems as well as the configurations between certain subsystems. It is the perception of both the developer. The timetable as well as the testing Plan are the only other papers that you'll have to plan.
The scheduling paper becomes easy maintenance to be doing if you already have carefully planned out technical requirements and concept documents, then you will have protected all of the bases.
Because while the functional specification is evaluated by decomposing higher-level components found towards lower-level mechanisms by requirement analysis phase. Lower roles are given the output potential contributing factor with either the greater position.
Addressing the complete system features is one part of the system specification. Certain functionality has been mostly carried out in hardware and some in applications. The specification including its framework is to describe the maximum functionality but to carry out trade-offs including preliminary design analyses to assign these specifications to the various disciplines, like that of the performance specifications.
