Value Engineering Methodology

The work proposed here will be evaluated through a well-established value engineering process. The first of three phases in this process is the Functional Analysis to define the scope of the readout system, including current design decisions in the context of the full project, as well as known requirements (performance, operational, environment, etc.). Each of the functions will be classified as basic or secondary through their connection to the flow down requirements. The second phase is the Alternative Analysis, which establishes which among the space of solutions could best meet project objectives relative to a reference design. For each of these options weighted criteria are defined (i.e. requirements, cost, schedule, production, operations, risks, complexity, flexibility, maintainability, safety, development cost/schedule) that will be used to evaluate the approaches. These considerations inform the weaknesses/risks that will be studied in a prioritized way through the above scenarios, subject to cost and schedule constraints. Through this phase, implications on cost, schedule, risks, and opportunities are evaluated and updated. Finally, the third phase is the Implementation in which the results of the Alternative Analysis with regard to scoring against the weighted criteria will be presented to the Project Office and/or a designated review team to arrive at a decision to either select or reject a design, or to do further work. Through this process, we will manage risk, maximize opportunity, and promote discussion and support for the final decisions.
