very clear!!!
With simple techniques defined for each step, it took almost 10 days to complete the job partially and it is still in the process. And this is for a very simple system and indeed painstaking. Your points will aid me further down.
Thank you so much
So far so good. I've improved my requirement formulation via your 12 activities on a simple case study.
Some concerns on emergent behavior of the system, is there a way to capture the strong and weak emergence properties of the system?
Let me revise requirement engineering process again
1-----> customer needs
2 --->formal requirements(contains "shall" statment)
3----->Technical or design requirements (contains functional, performance, special quality....attributes)...
It is true. Before we establish the Misssion, Goal and Objective statement for a project, there is something called stakeholder analysis. For instance, consider a strategic plan for an Asian market, in this case the customer interest would be entirely different and also their way of expressing...
I got the hard copy of Dan Raymer's Conceptual Design approach and indeed it is an excellent source book.I have used it in writing top level requirements for high lift system.
Thank you for the support
Bingo! I go with it. We could expect a revised version of standards in the coming years and I don’t know what modified PMTE definition it will carry to address the key challenges in design process.
My current work is to find an approach that allows the design synthesis to be a part of the SE...
Here comes "Model Based System Engineering" (MBSE), what does the future hold?
The attachment has something to say!!!http://files.engineering.com/getfile.aspx?folder=2005deaa-60f6-4acb-881c-75d38ca2ec86&file=MBSE_Methodology_Survey_RevA.pdf
So we are having different interpretation of the problem definition. Stating the problem is more difficult than stating the solution. This is what happening in current design department. We receive a customer need and there is an intermediator to translate this need into a system requirements as...
Certainly, this is the limitation set forth in expressing “a well-formed” requirement. Your example: the housing [system] shall provide the functions of environmental protection, EMI shielding, mechanical support of the optical windows [Action] can be reframed as “During xx time phase...
Well, most system engineers are former aerospace engineers who advance into systems engineering. They must take into account management in addition to other STRESS factors.
Well stated and thank you.
The general consensus is, there is no one single tool that could satisfy all the stakeholders in the loop. For a customer it doesn't matter how does it work and it is important for a designer to know how innovative work can add value to the business core value. Taking...
Hello,
I am currently pursuing a course degree in System engineering and I am a designer and aircraft engine performance analyst by profession.
Capturing the customer requirement is a critical issue in developing the right design specification for the system under context. There are tools...
