In her Personality Matters series, Leslie Sachs examines the personalities and people issues that are found in technology groups from cross-functional, high-performance teams to dysfunctional matrix organizations.
Many commercial tools vendors like IBM are learning to structure themselves much more like their open source counterparts, with full transparency into the defects that are being fixed and tasks being completed. Today, you can see plans for features, defects, and resources all exposed, even while working to compete with other commercial tools vendors in the same space.
Understanding the personality of tools and their vendors, whether they be commercial or open source, is a matter of understanding your organization's behavior. Corporations have personalities, too. As always in psychology, you need to be aware and knowledgeable about your own needs and capabilities. You will succeed if you can align your organization’s personality with the tools and processes that you want to implement. Feel free to drop me a line and let me know about your own challenges with understanding the interaction of personality and tools!
