Original Post Date: Wednesday, December 17, 2008 A recent Gartner report indicates that industry enthusiasm for SOA is waning.  The reasons cited are the lack of enough people with the proper skill sets to perform SOA deployments and the lack of a good business case for SOA.  It’s an interesting but not really unexpected direction.  SOA has been surrounded by significant hype, ensuring that organizations surveyed would be anxious to profess their desire to start a SOA project.  But as the rubber hits the road, these organizations are realizing that SOA may not be the answer to all of their ...
Wednesday, December 10, 2008 by Anthony DeMarco Technology readiness is a critical cost driver of development programs.  Many high technology programs fail because initial cost and schedule expectations were based on the assumption that the technologies employed were proven,  when actually they were not. Space programs have the most dubious history in this regard.  I once listened to a Lockheed Martin executive explain how the X33 space shuttle was a great vehicle, but was canceled because it was, "two inventions short of meeting the requirements". Canceled after over one billion dollars were spent. Starting development projects that have constrained budgets and ...
Original Post Date: Thursday, October 30, 2008  Software cost estimation is hard.  I have learned this the hard way – as a software developer and later as the manager of software development projects. Today, as a builder of cost estimating software, I learn something everyday about software development that reinforces the fact that software cost estimation is hard. I attend a lot of trade shows and I talk to a lot of software people about how they estimate software costs.  Many of them have no formal process, many don’t collect data as projects progress, many of them perform estimates off the ...
Original Post Date: Tuesday, October 7, 2008  Jacob has a great comment to my recent post on getting it "right the first time".  He notes that requirements are often fuzzy and that estimates rely on peoples' opinion of cost and duration - and that the are often wrong.  He asked what silver bullet we have. Our silver bullet is a proven discipline that makes people better estimators and sheds light on fuzzy requirements. It starts with the people. Becoming an accurate estimator requires the same step-by-step approach as any learned skill such as golf or tennis or swimming (things I ...
Original Post Date: Wednesday, October 1, 2008  As I prepare my remarks for the first PRICE Systems International Symposium and User Group Meeting in Asia hosted by the PRIGENT corporation, I am astounded by the recent globalization of the Defense Industry.  Worldwide weapon systems acquisition has been permanently changed by:  the merger of US defense contractors in the 1990's, the entry of European contractors into the US Defense Industry (EADS, BAE) in the 2000's, and the entry of Korea into the global market happening now. Today, BAE Systems ...
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, September 3, 2008 Productivity refers to measures of output from production processes, per unit of input. The labor and materials that go into a project are the input, and the final delivered product represents the output. Your estimated project budget determines the planned productivity, and decomposes to a planned productivity for each individual and each unit of material.  The dynamics of the Project Management Triangle tell us that for a fixed cost (input) and schedule, if I underestimate the scope (output), then I have planned for a lower than optimal productivity.  And Parkinson's Law law tells us 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 ...
