In two recent papers, David Chappell, Principal of Chappell & Associates, outlines the different aspects of software quality – functional, structural, and process-, the groups of people directly interested in quality –users, developers, and sponsors-, and the outcome of defects in externally or internally facing software over time.
A Coverity study concludes that open source code using static analysis has on average a lower number of defects than commercial code, but they are on par when it comes to code of similar sizes.
Tony Wong, a project management blackbelt, enumerates some practical points on individual procutivity. This article wonders how well these apply to software development and contrasts his list with that of other lists.
On the 1st November software engineer and author John R. Fox has published his book “Digital Work in an Analog World”.

There is a constant tussle between following Agile techniques and still managing to do enterprise architecture. While Agile development focuses on adjusting the design as more insight is gained, architecture establishes the technology stack and addresses quality attributes. Combination of the two is successful when agile techniques are leveraged to drive towards the desired architecture.
In lean manufacturing, the definition of inventory is pretty clear. It is the extra material, work in progress material and material queued up for the next bit of work. Lean emphasizes on reducing the inventory because there is always an inventory handling costs. In software development, often requirements are seen as inventory, what about the code?
The privately owned US company Coverity claims that its newly released and browser-based software tool Coverity Integrity Control supports development organizations to set standard policies for code quality and security, and then manage, monitor and report on these policies as code is tested.
Several members of the Agile community describe different styles for expressing user story tests and the testing of an entire theme.
James Whittaker, a former Microsoft architect, author of several books in the “How to Break Software” series, and currently Director of Test Engineering at Google, has written a series of posts on how Google does testing. Google blends development with testing, having relatively few testers, and each product goes through successive channels before is ready for prime time.
While, zero defects sounds very good to hear, is it really possible or is it an unachievable goal? Many organizations adopt a 'zero defects methodology'. Does it really mean anything?
Facebook is probably the hottest company today, driving a very high level of interest and scrutiny. Despite a high level of secrecy, Yee Lee, a product manager at Skype, has assembled a large collection of notes detailing how code ships at Facebook.
What can you do when unacceptable numbers of stories are "done" with development, but they still have many quality problems?
