Original Post Date: Tuesday, October 12, 2010 National Boss Day is quickly approaching! While October 16th is the actual day this year it will be observed on Oct 15th since the 16th falls on a Saturday and what boss wants to hear from his or her employees on a day off even to be showered with cards, flowers and accolades.  According to Barry Wood, Boss Day was started in 1958 when Patricia Bays Haroski of Deerfield Ill registered it as a special date with the US Chamber of Congress to honor her boss (who was also her father).  October ...
Original Post Date: Wednesday, October 6, 2010 The key cost driver when estimating software costs is the size of the product. The problem is that there is no perfect technique available to measure and quantify the size of software. The two major techniques in use today are Source Lines of Code and Function Points.  Today we will talk about Source Lines or Code or SLOC. Source Lines of Code measures logical lines of code. It takes some of the uncertainty out of physical line of code measures by counting only complete statements (which can cross over more than on physical line). SLOC excludes comments and blank ...
Original Post Date: Wednesday, September 29, 2010 Earlier this month Under Secretary of Defense, Asthon Carter, spoke at the 2010 Annual Air and Space Conference. His speech touched on some of the 5 categories that he and Defense Secretary Robert Gates laid out in order to identify low value activities and reapportion approximately $100 billion dollars within the Defense Budget to higher value capabilities needed to support US Forces. The first of those categories he described has to do with "targeting affordability".  In the context of a specific Navy program he explained this concept in a simple practical manner:  "The way to do that is ...
Original Post Date: Wednesday, September 29, 2010 Recently I came across the word “off-label”.  It is the term used by the medical community when a drug is used to treat a condition for which it has not been approved by the Food and Drug Administration.   We sometimes use TruePlanning for “off-label” purposes. A good example would be using the TruePlanning Calibration tool to answer such questions as, what is the maximum number of source lines of code (SLOC) I can get and remain within my budget?  I call this TruePlanning Optimization. Here is an example answering the SLOC question. First begin ...
Original Post Date: Thursday, July 29, 2010 The following is an extract from a paper written in 1978 from one of the founders of PRICE Systems:  Two questions are often asked by those unfamiliar with TruePlanning’s approach to cost modeling: What is your CER (cost estimating relationship)? And what is your data base? These questions are closely related.  Both are based on the assumption that the PRICE modeling approach is the same as that customarily used in developing cost estimating relationships.  This is not the case.  The customary approach is to first gather as much relevant data as possible, then screen the ...
Original Post Date: Tuesday, June 15, 2010  I recently read a great paper by Glenn Buttes and Kent Linton, NASA’s Joint Confidence Level Paradox – A History of Denial.   In it, the authors present a  very detailed analysis of many failed NASA projects along with some compelling theories on why so many projects fail and what can be done going forward.  While I’m not here to summarize their findings – interested parties can hit the link above and learn for themselves, there was one extremely interesting jewel in this paper that I felt the need to share. The reason I ...
Original Post Date: Thursday, June 10, 2010 This week I was thinking how useful the Export Import feature in TruePlanning can be. First, the Excel Import spreadsheet gives you an easy and convenient way to gather your data. In addition, it gives you an easy and convenient way to check and validate the data. When observing the data in a column format, it is so easy to spot and correct anomalies. Second, the Excel Import spreadsheet gives you an easy and convenient way to build your Product Breakdown Structure. No more inserting one cost object at a time. The Excel Import feature does it all ...
Original Post Date: Thursday, May 13, 2010  Earlier this week I conducted a webinar intended to make PRICE users aware of the Cost Research Services available to them as part of the license fee they pay to use PRICE products. I thought I would recap the highlights of this webinar for those of you who might have missed it. At PRICE we understand that cost estimating tools, while useful and valuable, do not always present the complete solution. Every single cost estimation projects presents new and unique challenges.  We think it's important that in addition to solid, time trusted cost estimating models, ...
Original Post Date: Thursday, May 6, 2010 I am excited about the efforts described in Derek Kaufman’s article on the AFMC website.  For the complete story please see this link http://www.afmc.af.mil/news/story.asp?id=123202181. The DoD is investing in the rapid build up of a new foundation of acquisition workers focused on estimating costs and negotiating prices through continuous learning.    Mr. Assad notes that Wright-Patterson Air Force Base, Ohio, was once the preeminent DoD recognized leader at estimating costs and negotiating prices with defense contractors. It's a skill that has been allowed to atrophy, he noted.   "We need to build that pricing capability back ...
Original Post Date: Friday, April 30, 2010 I have been frequently asked to do crosschecks on other people’s software cost estimates which are potentially done in a variety of tools from spreadsheets to SLIM. One of the common operator errors I see from other users is not understanding what activities and resources are included in the outputs of the particular tool that they are estimating with. This is akin to deciding between two cars and not knowing if both come with the same sets of features (stereo, AC, heated seats).   With software estimation tools you need to know what work is getting estimated ...
