Bug Counts vs. Test Coverage

Occasionally, we encounter projects where bug counts simply aren't as high as we expect. Perhaps the product under test is in its second or third release cycle, or maybe the development team invested an inordinate amount of time in unit testing. Whatever the reason, low bug counts can be a cause of concern because they can indicate that pieces of functionality (which potentially contain bugs) are being missed. When low bug counts are encountered, management may begin to wonder about the quality of testing. This article covers techniques for dealing with low bug counts, and methods for reassuring management that coverage is being achieved.

Failure Is Not an Option

This paper discusses the factors involved in determining the cost of a 24x7 e-commerce or internal Web site going offline for any length of time. After determining these costs, and showing a real-life example calculation, the paper then goes into several ways to minimize this risk via hardware architecture, software architecture, and stress testing.

This paper describes practices that have led to a sound and reliable build and deployment process at Hewlett-Packard. Two teams of engineers, later joined by a third, responsible for developing e-service components to build a Web application, chose to use open source development tools/utilities in the "Evolutionary Software Development Lifecycle" environment.

Extreme Programming Considered Harmful for Reliable Software Development

This paper presents data collected on extreme programming (XP) and how this method relates to traditional software engineering practices. The author presents reasons—albeit no scientific proofs—why extreme programming may be harmful to a reliable software development project. The paper also discusses why Extreme Programming fails to provide answers to significant questions that contemporary software development methods have to answer. The Extreme Programming hype, and its variant in the "Agile Methods" packaging, currently dominates the software development scene and should be investigated and evaluated before assuming it is the best method for a particular project. This paper is an attempt to contribute to the discussion.

Change Management

Companies need to be flexible and innovative in the ways in which they deal with the unfamiliar situations they often find themselves in. We are in a time of great change. The reality of yesterday proves wrong today, and nobody really knows what will be the truth tomorrow. The steadily increasing complexity of the world is asking too much of us. How can we, as individuals, as well as organizations, prepare ourselves for an uncertain future? Through creating our own future. Change management means empowering organizations and individuals for taking over their responsibility for their own future.

This paper describes the Challenges of Change faced by today's managers and how to cope with these challenges and lead the organization.

Establishing an Infrastructure for Immediate Servlet Testing

If you establish an appropriate infrastructure, you can perform client-side testing on a servlet immediately after you compile it and perform unit testing. Of course, testing early doesn't eliminate the need for later application-wide testing. However, it does improve the overall efficiency of your development process and make the later phases of testing decidedly less painful.
