Original Post Date: Wednesday, June 15, 2011 At the 2011 ISPA Conference, I conducted a ½ day workshop How To Develop Data-Driven Cost Estimating Relationships  in TruePlanning. The attendees at the workshop learned how to import their own data into TruePlanning and develop custom Cost Estimating Relationships. We covered three case studies:   ·         In the UCAS case study we demonstrated how we can build CERs at a higher level to provide a test of reasonableness to the CAPE. ·         In the SRDR case study we demonstrated how we develop a CER to estimate SLOC based on historical data and use the results ...
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: Friday, June 10, 2011 I’m on my way home from the ISPA/SCEA (International Society of Parametric Analysts, Society of Cost Estimating and Analysis) Conference held in Albuquerque this week.  Attendance was very good (2nd best in the conferences history) and as the content seemed especially good this week.  I attended lots of good talks on topics ranging from SEPM (System Engineering, Project Management) cost estimating, Joint Confidence Levels, Software Estimating, Affordability,  Agile software development and estimating for Enterprise Resource Planning Systems.   Of course, just because the topics are good and well presented doesn’t mean I have ...

Original Post Date: Friday, June 3, 2011  If I Google the phrase “cloud computing” I get about 49,900,000 hits.  That’s a lot of hits – more than 10 times the hits I get if I Google “service oriented architecture.”  This made me think that cloud computing is an area I needed to learn more about. So what are we really talking about when we talk about cloud computing?  “The cloud” is a generally accepted euphemism for the Internet.  End users access computing assets from the cloud using a model similar to one that homes and offices use to get electricity ...
Original Post Date: Wednesday, May 25, 2011  Going to ISPA SCEA in New Mexico?  If so, join us for a workshop on data driven cost estimating.  Description:  Building transparency and traceability into your estimating process leads to more defendable estimates.  This hands-on workshop demonstrates how historical data is transformed into predictive models.   You will learn how your organization’s data can be synthesized into custom models that can be employed in support of third party models within a single analytical framework.  Participants will learn:  (1)   To develop system level estimating relationships to provide a test of reasonableness and historical cross-check to proposed estimates. (2) To develop ...
Original Post Date: Thursday, May 19, 2011 I was recently asked by a client to provide a synopsis of what TruePlanning offers in response to the Ashton Carter Memorandum – Implementation of Will-Cost and Should-Cost Management. In the memo, the Undersecretary of Defense AT&L listed “Selected Ingredients of Should Cost Management”. It was interesting to note how much capability is provided by TruePlanning to effectively support efficient should cost management. In this month’s blog, I will share with my response to our client with you. ...
Original Post Date: Wednesday, May 18, 2011  Parametrics is more than estimating. It represents the complete process of capturing and utilizing (often with calibration) non-cost drivers, as well as associated programattics and configuration levels. The Wiki definition of systems engineering immediately speaks to project complexity, life cycle management, and logistics. Any question that parametrics and systems engineering are interrelated?  In many of our customer organizations, affordability and cost-benefit analyses have migrated to system engineering functions. How and where does your organization perform these analyses?  As we enhance our capabilities and applications, it’s beneficial for all concerned to understand your adaptation of parametrics within the core ...
Original Post Date: Wednesday, May 18, 2011 This week I am attending the Systems and Software Technology Conference 2011 in Salt Lake City.  I've been a regular at this conference for the last 20 years.  While attendance has declined, the conference continues to deliver quality content for developers and acquirers of software and software intensive systems.  The keynote was delivered by this year’s recipients of the prestigious Wayne Stevens Award.  Barry Boehm, one of the recipients was well known to everyone in the room and the software community.  He gave a great presentation reviewing his technology predictions from a paper presented in 2006 and offered predictions for 2011 ...
