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 ...
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: Monday, October 6, 2008  According to Gartner, Service Oriented Architectures (SOAs) will be used in more than eighty percent of mission critical operational applications and business processes by the year 2010.  Perusal of the literature on SOAs leads to visions of ease of implementation and cost savings of epic proportions.  And it is likely that not only will service oriented implementations results in cost savings, but that without them many currently envisioned capabilities in the corporate world and the Department of Defense (DoD) will be impossible to deploy, maintain, and evolve as technology explodes and requirements and ...
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: 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: 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 ...
