Original Post Date: Thursday, September 18, 2008 While many at Bear Stearns, Lehman Brothers, Merrill Lynch, and AIG are staggering from the Wall Street financial crisis, others on the acquisition side are contemplating the fate of redundant operations created by the these consolidations.  This reminds me of the rapid consolidation of the global Aerospace and Defense (A&D) during the 90's after the fall of the Berlin Wall.  Granted, this consolidation is happening at a much faster pace, but it would be wise for decision-makers to do a little performance measurement before they slash and burn redundant operations.  During the A&D consolidation, the General Electric Corporation called ...
Original Post Date: Wednesday, September 10, 2008 Martin Woodward ‘s comparison of software development to Sudoku does an excellent job of explaining why software cost estimation is hard.  We constantly hear about software development projects that are unsuccessful because they have violated one or more aspects of the Project Management Triangle  - they are either delivered late, delivered over budget or fail to deliver the capability that users require. And while I firmly believe that software development is an engineering discipline, software project estimation is often more complicated than estimation for other engineering disciplines because software project output is not nearly ...
Original Post Date: Wednesday, September 10, 2008 A good point is made in a comment to my last post, Chris Carter says, "As estimators I think it is our duty to tell our customer (management) what we assess the possible range of outcomes to be so that they can make use of this information ".  I agree that we should always deliver an indication of accuracy every estimate.  Uncertainty and risk analysis is an integral feature of TruePlanning and we educate our clients on the value of estimate ranges to optimizing project and portfolio performance. The uncertainty-based probabilistic confidence-level of an estimate that ...
Original Post Date: Wednesday, August 27, 2008 While working with clients who operate under fixed budgets I often hear, "Cost is not an issue when we plan and budget, so why is estimating important?".  I quickly stress that estimating is not just about cost.  It about balancing project scope, cost, time, benefits and risks. If your estimates are not accurate, your projects and portfolios are not optimized – and you are wasting money. Projects are planned and managed within scope, time, and cost constraints. These constraints are referred to as the Project Management Triangle.  Each side represents a constraint.  One side ...
Original Post Date: Friday, August 22, 2008 Software size measurement continues to be a contentious issue within the software industry.  While the software engineering community has made significant progress in it’s quest for the right way to assign value, the journey has not been without missteps and detours.  And there is still more work to be done. When I first started programming it never occurred to me to think about the size of the software I was developing.  This was true for several reasons.  First of all, back in the day, software had a tactile quality through the deck of punched ...
Original Post Date: Tuesday, August 19, 2008 Recently a client approached me with a thought provoking inquiry.  They were interested in performing historical trend analysis on their software projects to support estimating software costs for future technologies.  They have done this for years with hardware procurements and wanted to start performing the same kind of analysis for software. For hardware it’s not that hard to do, we have tangibles like RAM size, processor speed, resolution, etc. The question they had for me was “What are likely candidates on which to perform historical trend analysis for software”.  Think about it.  What ...
Original Post Date: Tuesday, August 12, 2008 I frequently attend trade shows and conferences focused on software development and/or cost estimating.  These shows provide a great opportunity for me to perform informal, unscientific surveys of the state of the software estimating discipline.  When queried on software estimating practices, more than half of those surveyed indicate a method that significantly resembles some attraction at a local carnival.  To the follow up question of “How’s that working for you?” the reply is almost always as expected – “Not too well”. As an industry we have failed pretty miserably at institutionalizing software estimating ...
Original Post Date: Wednesday, August 6, 2008 Last week the U.S. Senate Committee on Homeland Security and Governmental Affairs held a hearing entitled "Offline and Off-budget: The Dismal State of Information Technology Planning in the Federal Government".  The prepared remarks by those who testified before the committee make good reading.  You can find them here. The committee focused on the many IT projects that are overrunning cost and schedule, giving most Federal Agencies failing grades on their budget management report card.  My experience while working with Fortune 500 companies is that they do not do much better - we just do ...
Original Post Date: Friday, August 1, 2008 If you are a baby-boomer like me and occasionally suffer from symptoms of mid-life crises it is important to answer the question, " What is the purpose of my work, my mission, my raison d'être?" So, I am starting this blog by taking a step away from the challenges on my desk at the moment to look at the big picture. Business leaders agree that reliable shareholder value lies in companies that sustain profitable growth and are "built to last". Hence, leaders focus on improving key performance indicators (KPIs) throughout their companies to ...
