1. In accomplishing needs analysis in response to given deficiency, what type of information you would include? Describe the process that you would use in developing necessary information? Information required to accomplish needs analysis in response to given deficiency is statement of problem presented in specific quantitative and qualitative terms and with enough detail to justify progressing to next step. Problem statement must reflect true customer requirements. Having defined the problem completely and thoroughly, a needs analysis should be performed with the objective of translating a broadly defined WANT into more specific system level requirement. The questions are as follows: What is required of the system in functional terms? What functions must the system perform? What are the primary functions? What are the secondary functions? What must be accomplished to alleviate the stated deficiency? When must this be accomplished? Where is it to be accomplished? How many times or at what frequency must this be accomplished? There are basic questions of this nature, making it important to describe the customer requirements in a functional manner to avoid a premature commitment to a specific design concept or configuration. Unless form follows function, there is likely to be an un-necessary expenditure of valuable resources. The ultimate objective is to define the WHAT’s first, deferring the HOW’s until later. Information necessary for accomplishing needs analysis is developed using the team approach process. Team approach is involving of customers, consumers, producers, suppliers as appropriate in order to identify the problem and define WHATs first. The objective of team approach process is to establish effective communicat... ... middle of paper ... ...ation rate and so on. There may be any number or combination of TPM values for a particular system during the conceptual design phase. The objective is to influence the system design process to incorporate the right characteristics to produce a system that will ultimately meet customer requirements effectively and efficiently. Reasons for using TPMs are as follows: • TPMs are used to forecast values to be achieved through planned technical effort. • TPMs provide visibility of actual versus planned performance. • TPMs provide early detection of problems requiring management attention. • TPMs are used to mitigate risk during design and manufacturing.
