Question:

In this weeks course material, we discussed design, and evaluation of designs.  The concept of evalating the design to make sure it fulfills requirements correctly is so critical that the textbook devotes and entire chapter to it, Chapter 5.  After reading Chapter 5, please answer the following questions at the end of the chapter (page 264):

1, 3, 5, 6, 7, 8, 9, 10, and 13. 

Answer each question is as much detail as you can.  Your submission should be between 1 and 2 pages.  Please adhere to the typographic format in the Start Here folder.

I attached the questions and answers from my friends, u can just follow his idea what he did and change the words, don’t copy it please.

1. Describe the checks and balances in the design process (as you see them).

The checks and balances is a process that occurs earlier in the design process. While undertaking a new project it is really important to create an estimate for balances and the budget of the project since budget plays a vital role in the process. Any changes to this process can be done with relative ease and without any extra cost. This process is really vital and should be incorporated in order to ensure that system configuration is properly developed and properly tailored for the requirement specified by the client.

3. What is included in the establishment of a “functional” baseline? “Allocated” baseline? “product”

baseline? Why is baseline management important?

Functional baseline includes the operational requirements and the maintenance concept, the result of the feasibility analysis, trade off study reports, identification of technical performance measures and the system specification. On the other hand Allocated baseline is defined through steps such as combination of development, process, product and also material specifications. Product baseline usually contains the releasable contents of a project and is defined through the configuration of the project. Baseline management is important because it helps us understand the processes and the configuration involved with a project. It also helps us identify the activities and milestones involved with the system acquisition process.

5. Identify some of the benefits derived through formal design review. Describe some concerns.

Formal design review allows the engineers and the personals involved with the project to identify the problem before it takes place. The system verification process allows us to detect the problem and then offer a possible solution to fix the flaw in the design before it’s been implemented. Making changes to the design process in the earlier stages allows a quick and a more cost effective fix. The formal design review is an important as a medium for communication and it involves the review and approval of the final design by a skilled and experienced engineer. Communication is really vital in the final design process as it involves discussion and approval of numerous engineers and officers involved with the design process to finalize the design. This basically leaves less room for error in the final design and it also ensures that the final design will be made flawless.

6. In developing an agenda in preparing for a formal design review, what considerations must be addressed in

the selection of items to be covered in the review process? How are review and evaluation criteria identified? Describe the steps and resources required in preparing for the design review.

An Agenda for the project should be able to define the scope and anticipated objectives or goals for the project. Review and evaluation criteria are identified after the completion of the detail design process before the final design has been approved for the project. A design review process usually involves 5 steps the first step before starting the design review is to compile all the documentation needed for the evaluation. The second involves analyzing the design using the predictions, tradeoffs and evaluation results. The third step involves using TPMs configuration to analyze the final design. The fourth step involves the use of a detail production plan and the final or the 5th step involves implementing the final logistics and maintenance support plan.

7. How are technical performance measures (TPMs) considered in the design review process?

The Technical performance measures (TPMs) is a part of the design process that involves the review of the assessment of the proposed system design configuration. TPM’s is a constant process that involves review of the design through each step of the design process in order to ensure that the system level requirement is maintained through different stages of design and development.

9. How are design changes initiated? How are priorities established?

In the engineering process the design when initiated for change is categorized under “urgent”, “emergency” or either “routine”. The design is then approached based on what it has been categorized under. The changes initiated are also categorized under two categorizes either Class 1 or Class 2. Class 1 represents the change in design which will affect the form and functional changes of the design; the overall goal of this change is to target the system performance, reliability, safety, etc. And similarly Class 2 represents minor changes in the design which are not bound to cause any changes in the performance or the functionality of the design and it will also not impact the system requirements.

10. How are design changes implemented? Identify the steps involved in system modifications.

After a flaw in the original design has been recognized there are series of steps or procedures that has to be undergone in order to initiate changes in the design. First an engineering proposal is developed through the review of the design, the engineering proposal recognizes the flaw in the design and then initiates changes required to modify the design and remove the flaws. The design changes in initiated after engineering proposal has been passed, A design changes generally involves two steps the development of modification kits or tools and installation procedures and revision of supporting documentation for the design.

13. How does configuration management (CM) relate to system engineering? Why is it important? What is

likely to occur if configuration management practices(or equivalent) are not followed?

Configuration management (CM) relates to system engineering through Baseline management. In an engineering system Baseline are established as the system development process evolves. It’s relation with the Baseline makes it a vital agent system engineering. Any changes or variation with respect to baseline is tightly controlled and vital for the overall System. It is really important to record and document all the changes that a system goes through for evaluating the impact of the overall system requirements. It is really important that the configuration management practices are properly followed any failure to follow these steps of configuration management will result in failure in control of changes and it also lead to a failure in maintaining the integrity of the overall design.
