The second group deals with tools. A person is only as good as the tools allow. The list of tools might include compilers, CASE, debuggers, DCE, CORBA, version control tools, project management tools, source control tools, life cycle tools, quality assurance and testing tools, database and transaction processing tools, bug and error report tracking systems, code test coverage tools, memory leak tools, change management, interface control, rapid prototyping, error and event management, event simulation, information sharing and file systems, security, and many, many more. Of course, two of the most important decisions are the operating system and the hardware.
