Original Post Date: Wednesday, September 25, 2013 During a recent Analysis of Alternatives (“AoA”) consulting project, our customer asked that we provide more insight into TruePlanning’s System and Assembly objects, which in our AoA context we termed Systems Engineering/ Program Management (SE/PM) and Alternative Integration/ Test, respectively. The customer’s challenge was understanding our parametric model’s treatment of principally hardware-COTS objects, combined with other cost, purchased service and training objects.Our Chief Scientist, Arlene Minkiewicz, provided us with insights that I’d like to share with you, as well as my views on how we at PRICE systems have consistently used these parent ...
Original Post Date: Thursday, November 29, 2012 With Customize View, TruePlanning™ offers great flexibility in editing favorites as row by column grids.  Typical examples are Object by Activity, Object by Resource and Activity by Resource.  But what if you wanted to view any of these grids also by year?  In other words, how can we add a third dimension?  Last October, in my “Work Breakdown Structures are Workable!” blog, we discussed the use of Excel’s Data-Sort and Data-Group options to build up a WBS, for a MIL-STD 881 style view of Activity by Object as a linear list.  Results were singular ...
Original Post Date: Wednesday, October 17, 2012 A frequent question from students and consulting clients is how to estimate software size when either: detailed functional requirements descriptions are not yet documented or, even if the latter do exist, the resources necessary (in cost and time) for detailed function point (“FP”) counting are prohibitive. If appropriate analogies or detailed use cases are not available, fast function point counting can be a non-starter, without nominal understanding of pre-design software transactions and data functions.  Hence, the challenge is to find an estimating basis for functional measure (i.e., ...
Original Post Date: Wednesday, July 20, 2011 Electronics Complexity and Quality Levels…   The PRICE Calculator for Electronics Manufacturing Complexity, shown below, has a subtle but very powerful feature for Quality Adjustment, based on Mil-Hdbk-217E Quality Levels.    The above shows “None” which yields the standard MCPLXE, in this case a 8.07 value applying 100% Large Scale Integrated Circuits for Display (with CRT) equipment as an example. Yet, in the course of estimating a mission-critical automatic tester  with multiple controller-card assemblies for an airborne-military platform, I adjusted for more stringent quality levels—specifically “S-1” level consistent with Mil-Std-975/ Mil-Std-1547 per below.   Note that ...
Original Post Date: Wednesday, June 15, 2011 While teaching an introductory TruePlanning for Software Estimating course this week at an Army location, I was asked to follow up with a clarification on “percent adapted” calculation.  The official PRICE training materials definitions are:   • Percent of Design Adapted - the percentage of the existing (adapted code) design that must change to enable the adapted code to function and meet the software project requirements;   • Percent of Code Adapted - the percentage of the adapted code that must change to enable the adapted code to function and meet the software project requirements.   The former, Design, ...
Original Post Date: Thursday, February 17, 2011 My June blog entry suggested the use of parametrics in real-options valuation. This month, I’d like to offer the generalized use of our type of modeling in valuing tangible assets.  Typically, fundamental analysis evaluates the intrinsic value of securities. I won’t attempt to compete with Warren Buffet here. But it is certainly the case that a company, or portfolio of securities reflecting many companies, is based in part on the market value of its product assets and their potential for future earnings, as well as other objective and subjective considerations. In parametric estimation, we take a top-down ...
