FP Lite - An Alternative Approach to Sizing

Past criticisms of Function Point Analysis (FPA) have included concerns that it takes too long, it requires too much detail, it is too difficult to implement, and it costs too much. A recent study has shown that an adaptation of the FPA methodology – FP Lite™ – is a reasonable alternative to the detailed FPA method, and in fact, addresses many of the criticisms that have been levied in the past. This paper introduces the FP Lite™ methodology in correlation with two studies designed to statistically understand the accuracy of the FP Lite™ methodology in contrast to the detailed FPA method.

Why Can't We Estimate Better?

Everyone agrees that software estimating continues to be an ongoing problem for IT managers. Sometimes there is a perception that an estimation model is a black box with a magic process from which the absolute answer appears, when an estimate is just that – an estimate. We need to reframe our thinking about estimating and view it as a vehicle to manage customer and management expectations based on the best available information at that point in time.

Using TMMi To Deliver Higher Quality Software

The average cost to fix a defect at the end of the lifecycle is 400-800 times greater than if it were addressed earlier. On average, poor requirement practices account for 60 percent of a project’s time and budget. Organizations with well-defined, closely managed, and effectively measured quality activities succeed and continuously improve. Yet, in a recent survey, 77 percent of managers reported that bad decisions have been made due to a lack of accurate information.

This presentation outlines the TMMi model, the de facto international standard to assess and improve test maturity, featuring independent best practices from more than 14 quality and test models. It explores how TMMI can be used in conjunction with the GQM model to ensure that upper management is provided with the information they need to make informed business decisions.

"It's frustrating that there are so many failed software projects when I know from personal experience that it's possible to do so much better - and we can help."
