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 ...
Original Post Date: Friday, February 11, 2011 The DoD Cost Analysis Symposium (DODCAS 2011) is next week, Feb 15-18.  I’ll be there along with several of my colleagues at PRICE Systems.  This conference consistently provides an excellent source of information and shared experiences for the acquisition community and I am anxious to attend again this year.  Last year the conference occurred shortly after Congress passed the Weapons System Acquisition Reform Act of 2009 (WSARA) - and the majority of the sessions were focused on discussions about how the services, contractors and the government leadership planned on dealing with this new law.  From ...
Original Post Date: Monday, January 17, 2011 While I don’t like to admit to visiting a website entitled geekArticles.com, I did stumble across a reprint of an essay by Grant Rule “Bees and the Art of Estimating”  that some of you may find interesting and instructive.  The author participates in his own form of “Estimation Trivia” by posing the following challenge “Take paper and pencil and write your estimate for the number of insects in the average hive of English honeybees.”  Of the approximately 1100 software measurement and process improvement professionals he has challenged thusly,  only about 10 have ...
Original Post Date: Wednesday, January 12, 2011  TruePlanning 2010 SR1 estimation software is now available as an upgrade for existing PRICE customers. The most significant update to this version of TruePlanning is the capability to use both parametric estimating models as well as analogous data to produce estimates. This capability validates and increases the defensibility of estimates. TruePlanning provides a framework that allows content driven parametric models to be estimated in one system. Most notably, hardware, software, IT and Systems of Systems (SoS). No other commercially available estimating tool can make that claim. However, whereas in previous versions estimates relied on ...
Original Post Date: Thursday, January 6, 2011 Today, PRICE Systems, Senior Research Analyst, Bob Koury, will be presenting on Will Cost/Should Cost management. The presentation will focus on two main requirements mandated in the Ash Carter memo (mentioned here several times): Developing Should Cost/Will Cost targets and establishing Affordability as a requirement.  An example will be provided of how parametric estimating models were used to establish “Should Cost” targets and how they can be used by a budget authority (government or Industry) to be an informed consumer of contractor or sub-contractor bids. The demonstration portion of this webinar will focus on ...
Original Post Date: Friday, December 3, 2010 Yesterday I had the pleasure of speaking at the New England SCEA Chapter December. The attendees were a great mix of experienced, seasoned cost estimators and young, new talent, eager to learn techniques to apply on the job.  My topic was the program management value of combining estimating Rules of Thumb with more rigorous cost estimating models and databases [link to presentation .pdf].  Rule of Thumb estimating is used every day by program managers to help guide their projects.  Oversight authorities rarely have the resources to perform detailed program estimates, so they ...
Original Post Date: Wednesday, November 17, 2010 Recently a cost research project on missiles was completed. The research resulted in performance based equations for air-to-ground and surface-to-air missiles were developed. The performance based equations can be used for early concept estimation  on missile development and production costs. The question though is “What is the process for developing this type of estimating relationship?” This will be the first of a series of BLOGs on this topic.  The first task is to define what is a “Performance Based Equation?” Bruce Fad covered this definition in a previous “Data Driven BLOG” so please review his post for the details. The second step ...
Original Post Date: Monday, November 15, 2010 Last week I attended the 25th International Forum on COCOMO and Systems/Software Cost Modeling.  I attended for several reasons.  First of all, I was invited to participate on a panel whose topic was “25 years of Software Estimation: Lessons Learned, Challenges and Opportunities”.  Secondly, I have attended in the past and while it’s generally a small group, as such conferences go, I always come away impressed by the fact that so many smart people end up in one room and this year was no different.   But I digress; I really wanted to share ...
Original Post Date: Tuesday, November 2, 2010  After some recent meetings with clients I am sensing some confusion on how to estimate software reuse. I think part of the problem is in the definition of reuse, so let's start with a definition and then address the estimating issue. Software reuse is defined as “the use of existing software, or software knowledge, to build new software.” This definition came from Wikipedia. From a estimating software costs perspective the above definition is part of the problem. The definition should read: "Use of existing software with no changes for operation in the new software program.”  If the existing software is going to be changed, ...
Original Post Date: Wednesday, October 27, 2010 Here’s a cool project.  The Bloodhound Project  is focused on building a land vehicle capable of breaking the 1000mph speed barrier.  The mission of the project is twofold.  The first is to “overcome the impossible using science, technology, engineering and mathematics”.  But the second is more interesting – this project is intended as motivation for the upcoming generation to embrace technology related fields.  Britain doesn’t have enough students interested in such fields and they are worried about their ability to compete in technological forays going forward. But how much should something like this ...
