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: 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: Tuesday, March 29, 2011 “I think we have an obligation to work with industry to ensure that our suppliers do not just remain world class in defence, but aspire to be world-class manufactures that can withstand comparison to other industries.” Chief of Defence Procurement, Sir Robert Walmsley Is this a practical proposition or is it a pipe dream?  The following excerpt from Dale Shermon’s Systems Cost Engineering attempts to make the case that this type of comparison is possible. Many of the statements in proposals and marketing literature stating the superiority of a company are anecdotal or at best qualitative ...
Original Post Date: Wednesday, March 16, 2011 ...wear the worst shoes. The cobbler was a master at his craft; he was just too tired to practice it when he got home from the shop.  Sound familiar? A disciplined approach to understanding (functional) requirements as well as analogous projects (with actuals) is our not-so-secret sauce. Why run the risk of creeping back up our career learning curve? There’s already enough scope creep to keep us busy. Plus, for you management types charged with prospecting, a consistent approach towards estimation is a great way to connect with people who've felt the pain of being the cobbler's kids. I recently reconnected ...
Original Post Date: Wednesday, March 16, 2011 In Parametrics is Free, I acknowledged receiving (too late) “you should’ve known to ask that” over the years. Quality control after-the-fact is fine; but it’s better and cheaper to take a systematic approach to quality assurance as part of your estimating process. The sheer volume of what we model can often keep us so close to the details that we are unable to step back and put on our QA hat on for a sanity check. Enter Quality! On a very large project, our team has introduced a few regular cross-checks, notwithstanding typical math check-sums.   A round table peer ...
Original Post Date: Friday, March 4, 2011 I consistently run into this idea of data driven estimating.  Yet, there is no clear explanation of this concept.  I am not trying to provide one here, however, I am interested in is what is at the root of this growing movement.  My take is that it is an attempt to scratch an itch.  But what’s the itch? I believe it is related to my early post (Accuracy is Risky Business).  In the struggle to answer the accuracy question people have decided that understanding the data used in the estimating process is key ...
Original Post Date: Tuesday, March 1, 2011 The concept of the fuel cell was first published in 1938 by Christian Friedrich Schonbein.  Based on this publication Sir William Grove invented the precursor of the fuel cell in 1839. The Grove Cell created current by applying two acids to zinc and platinum electrodes separated by a porous ceramic pot.  In 1842 Grove developed the first actual fuel cell which produced electricity with hydrogen and oxygen, much like many fuel cells in use today. Fuel cells remained an intellectual curiosity until the 1960’s when the US space program identified a requirement for ...
Original Post Date: Friday, February 25, 2011 PRICE Systems is currently developing a COM interface for TruePlanning. I know, I know…  What’s COM you say? COM stands for (Component Object Model) and it's a programmable interface which exposes the TruePlanning estimating brains for integration and analysis!  I know it sounds boring but it’s really cool because it allows anyone, including our users, to build “apps” for TruePlanning similar to the way “apps” are built for the iPhone.  Let me give you some examples of some apps that you can build:  Excel solution, sensitivity analysis,  project comparison, risk simulation, total cost of ...
Original Post Date: Wednesday, February 23, 2011 In the world of estimating, accuracy is the first question out of people’s mouths.  Above all else they want to know the accuracy of an estimate.  How accurate is that approximate judgment?  Craziness! True accuracy can only be determined after the project or effort has been completed and a post-audit analysis reconciles what was expected to happen with what did happen.  This is a very expensive, time consuming process that many preach about but few actually attempt.  In my experience, when people ask about accuracy what they are really interested in is ...
