Technical Analysis

In during process of technical analysis the analyst evaluates the technical merits of the system concept at the similar time collecting additional information about reliability, performance, reducibility and maintainability. Some cases this system analysis step also includes a limited amount of design and research.

The Technical analysis starts with an assessment of the technical viability of the proposed system. What technologies are needed to accomplish system performance and function? What new methods, material, algorithms are processes are needed and what is their development risk? How will these technology issues affect on cost?

The various tools available for technical analysis are derived from mathematical optimization techniques and modeling probability and statistics queuing control theory and theory to name a few. It is important to note that analytical evaluation is not always possible.  Modelling either physical or mathematical is an effectual mechanism for technical analysis.

Fabrycky and Blanchard [BLA81} describe a group of criteria for the use of models during technical analysis of systems:

1.  The model should present the dynamics of the system configuration being evaluated in a path which is simple enough to manipulate and understand and still close enough to the operating reality to yield results.

2.  Models should highlight those factors which are most relevant to the problem at suppress and hand with discretion those which are not as important.

3.  The model should be made comprehensive through including all relevant factors and should be reliable in terms of repeatability of results.

4.  The Model design should be simple enough to allow for timely implementation in problem solving

Unless the model can be utilized in an efficient and timely manner through the manager or the analyst it is of little value. If the model is highly and large complex it may be appropriate to establish a series of smaller models in which the output of one can be tied to the input of another. Also it may be desirable to evaluate an exact part of the system independently from other component.

5.   The Models design should incorporate provisions for simple of modification and/or expansion to permit the assessment of additional factors as needed. Successful model development often includes a series of trials previously the overall target is met. Initial attempts may suggest information gaps that are not immediately consequently and apparent may suggest advantages changes.

The consequences obtained by technical analysis form the basis for another go or no-go decision on the system if technical risk is severe if models indicate which desired performance or function cannot be achieved if the pieces just won't fit together smoothly - it's back to the drawing board!
