Software Measurement Programs

A metrics program is any planned activity in which you use measurement to meet some specific goal. If you do not have a clear technical goal for a metrics program, then you are almost certainly not ready for such a program. Here's how to design a measurement program that leads to decisions and actions.

Finding the Signal through the Noise

A major challenge for software professionals interpreting data is deciding what's real and what isn't, what matters and what doesn't. A useful way to think about it is that you are trying to find the signal in the noise produced by random variation and error. Here is advice on how to extract the useful information from the "noise."

How Good Is This Software?—A Model to Measure Subjective Data

How do you really know how good your software is? Many traditional measures only look at the quantitative aspects of quality. Here's a model to measure and analyze subjective—or qualitative—data about software quality.

Customer Satisfaction: What to Ask, How to Ask, and Who to Ask

Improving customer satisfaction should be a primary goal of process improvement programs. So how satisfied are our customers? One of the best ways to find out is to ask them. Here are techniques for creating a useful survey and interpreting the results.

The Quality Barometer

A QA manager is often faced with measuring the impossible. Here is a simple, post-ship metric to help judge the test effort's effectiveness. The Quality Barometer method uses the bug counts found during testing, calculates a percentage, and then uses that percentage as the defect target number that can be tolerated after shipment.

Cem Kaner on Rethinking Software Metrics

The theory underlying a measurement must take into account at least nine factors. This article defines these nine factors (e.g., the scope of the measurement, the scale of the instrument, and the variation of measurements made with the instrument) and applies them to a few examples.

Software Sizing: There is an Easier Way

Project managers and software engineers need to accurately calculate delivery dates and resource needs for their software. This means they have to measure the size of the requirement, and estimate how much it will require in time and expense. But is there a sizing technique that's both effective and efficient? Popular sizing techniques such as the function point method can be difficult and labor intensive. However, there are alternative methods that produce quicker results, often without compromising accuracy. This presentation shares new ways to determine the size of your software deliverable while maintaining accuracy.

STAREAST 2001: Managing the End Game of a Software Project

How do you know when a product is ready to ship? QA managers have been faced with this question for many years. Using the methodology discussed in this presentation, you take the guessing out of shipping a product and replace it with key metrics to help you rationally make the right decision. Learn how to estimate, predict, and manage your software project as it gets closer to its release date. Learn how to define which metrics to track--and how to measure them. Discover how to define the ratings scale for each metric and how to create a spider chart for product readiness. This presentation is a must for any individual or organization that is serious about maximizing the results of positive events and minimizing the consequences of adverse ones.
