What is top level system design?
Definition: In acquisition-oriented systems engineering, a top-level system design represents the envisioned implementation of a system in sufficient detail to support credible projections of cost, schedule, performance, evolution, and risk. A top-level system design can be used to assess system feasibility at the outset of a program, as a basis for performing analyses of alternatives, and as a tool to help finalize requirements and budgets prior to a system development contract solicitation. When developed with careful consideration of its purpose, the top-level system design becomes the program's early technical baseline for acquisition planning activities.

What are the consequences of basing a program plan on a single top-level system design?
hardware solutions, or reuse of extensive existing products vs. new development). In this case, basing the program plans on a single top-level system design may have negative consequences because it could result in the development of system requirements that would preclude the bid of one (or more) contractors or result in unrealistic program cost/schedule estimates. In this instance, the SE should help evaluate the alternatives, identify and consider their pros and cons, and carefully decide which top-level system designs should be developed and carried forward into program planning to cover the range of implementation options.
What is the best way for program offices to obtain reliable projections of cost, schedule, performance, and risk?
One of the cornerstones of the program's systems engineering approach is the conviction that the best way for program offices to obtain reliable projections of cost, schedule, performance, and risk is through independent analysis . A comprehensive top-level system design, together with a government team with enough subject matter expertise to develop and use it, is the crucial enabler for such analysis. The following lessons learned are based on MITRE’s experience with the government acquisition program.
Why should top level design be avoided?
Additional "bells and whistles" may be exciting, but they should be avoided because in the long run they risk breaking the program's bank. Design depth.
Why is depth important in a system design?
Depth is key. To support meaningful assessments of feasibility, cost, and performance, a top-level system design must be detailed enough to identify and describe critical items. The level of detail needed to get to "critical items" depends on enabling technology, requirements, and the like.
Is it reasonable to use "maintain" or "manage" in a requirement statement?
NOTE: Use of terms such as ‘maintain’ or ‘manage ’ in a requirement statement is normally considered unclear, and to be avoided. However, there can be valid uses of these terms in HLRs. For example, it is perfectly reasonable to express a need for a Customer to ‘maintain ’ their account details.
Do stakeholders distinguish between high level and detail requirements?
Stakeholders, as a rule, do not distinguish between high-level and detail requirements. Nor do they appreciate being invited to discuss their [high-level] needs and hearing that some of those needs are ‘too detailed’ - that they will have to participate in yet another [detail requirements] conversation at a later date.
About
The Requirements Management process maintains a current and approved set of requirements over the entire acquisition life cycle. This helps ensure delivery of a capability that meets the intended mission performance, as stipulated by the operational user.
User Needs
The end-user needs are usually identified in operational terms at the system level during implementation of the Stakeholder Requirements Definition and Requirements Analysis processes (see DAG CH 3–4.2.1. Stakeholder Requirements Definition Process and 4.2.2. Requirements Analysis Process, respectively).
Traceability
Requirements Management provides bottom-up traceability from any derived lower-level requirement up to the applicable source (system-level requirement) from which it originates. This bi-directional traceability is the key to effective management of system requirements.
Benefits
Robust Requirements Management, implemented in synchronization with the program’s Configuration Management process (see DAG CH 3–4.1.6. Configuration Management Process ), can help the program to avoid or mitigate unintended or unanticipated consequences of changes through rigorous documentation of the system performance specification.
Requirements Management Activities and Products
The Program Manager (PM) should keep leadership and all stakeholders informed of cost, schedule and performance impacts associated with requirement changes and requirements growth.
