Original Post Date: Tuesday, November 8, 2011  Last week I attended the 26th annual COCOMO forum.  This meeting is an interesting combination of conference and working group and for me it’s a great place to take the pulse of the software and systems estimating community.  Lots of times you’ll go to a conference like this and feel as though the same old things are repeated year after year.  Not so with this conference – it is always a great mix of seasoned practitioners and graduate students with both groups providing forward looking information and inspiration on a variety of ...
Original Post Date: Thursday, October 20, 2011  Check out this article.   “Why IT Projects May be Riskier than you Think”.  If you read through the comments you will see that this article truly resonates with many in the field.  In the article the authors discuss research of over 1471 IT projects (large projects with an average cost of $167 million) comparing budgets and expected performance with actual costs and results.  Their results were surprising in that the average overrun was only 27%.  Turns out that the average isn’t what requires study but rather the outliers.  The study found that ...
Original Post Date: Monday, October 3, 2011 Here’s an interesting article “Technical Debt as Metaphor for Future Cost” ().  In this the author discusses the acceptability of using the metaphor of technical debt to facilitate communications between business leaders and the software team when negotiating around the triangle  (time, money, scope).   And while the  author accepts the use of this metaphor good “short-hand” for communicating the fact that avoiding the work now is not sparing the cost but just rearranging the way the costs are incurred – and often increasing the overall costs that need to be spent.  The ...
Original Post Date: Friday, September 2, 2011  The IEEE published “Top 11 Technologies of the Decade” in the  January 2011 editions of the IEEE Spectrum magazine.  It should come to a surprise to no one that the Smartphone was number 1 on this list.  The answer to the author’s question “Is your phone smarter than a fifth grader” was a resounding YES![1]   In 1983 Motorola introduced the first hand hell cellular phone.  It weighed in at two and a half pounds, had memory capacity for 30 phone numbers, took 10 hours to recharge and had a selling price of $4000 ...
Original Post Date: Thursday, August 25, 2011  Check out this Report on Big Data from McKinsey & Company published in June 2011.  Back in the day, when personal computers were becoming widely accepted and Microsoft Windows© was the new cool thing, SneakerNet was a common means of sharing data.   Certainly the introduction and subsequent improvements of networking technology and the Internet have made data sharing a whole lot easier and quicker.  But the concept of Big Data creates a whole new level of opportunity and potential for collecting and using data in ways heretofore unthinkable. So what is Big Data?   According ...
Original Post Date: Monday, July 11, 2011 There is a ton of code out there and we’re constantly adding more.  Gartner reported in 2009 that there were more than 310 billion lines of code in use worldwide. MS Word has grown from 27,000 lines of code in the first version to about 2 million in 2010.  The Windows Operating System grew from 3 million lines of code in 1992 to 20 Million in 1998.  You get the point – there’s lots of code out there doing lots of the same things that we may want our software to do. One ...
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: 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 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: 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 ...
