Developing reliable software on time and within(31)represents a difficult endeavor for many organizations.Usually business solutions have three main aspects:people,(32), and technology. The main reason for failing software projects has little to do with technology and tools, and much to do with lack of process(33). Experience has shown that introducing new technology and tools in an immature or undisciplined environment is likely to increase the chaos. CASE tools are not enough. "A fool with a tool is still a fool?"Structured method was the first wave of the software industry. This was the beginning of transforming software development from a"(34)industry' to mass production. Software process movement if the second wave in the software industry. The process maturity movement prepares the way for the third wave of the software industry: "software industrialization". Software development will become like an assembly and manufacturing process. A critical enabling factor is a disciplined software engineering process with predictable quality,(35)and functionality.
