China Official language is Chinese Software education & training by using Chinese It is not most important reason, since Korea has been superior to China in software export. Languages

  22. India More oversea Indians participants Oversea Indians bring in not only software knowledge, tech. & management experience, but also funds & outsourcing contracts. China Less oversea Chinese participants China needs more oversea Chinese to make contribution to her software industry. Oversea Participant

  23. What is major experience in India & What Is Key Issue in China? • What is the core technology of software industry? It is that how to • produce a software with satisfactory quality – a process thinking! • Software quality is the function of talent resource, process and • technology: • Q = f (M, P, T) • where Q represents quality, M indicates talent resource and T is technology. • The major experience from India’s software industry is its software quality • assurance(SQA) which is generated by its industrialized production • and mature software engineering (process) management. • Does China lack talent resource? No. The key issue of China is that China • lower maturity of software process management and its manual workshop • production model.

  24. How Does Software Workshop Become Software Enterprise? • Thinking In Software Engineering & Doing by SE. Software design, • development, testing, maintenance and management is a system engineering • which is a combination of multiply subjects. For example System Engineering Automatic Control Project Management Fuzzy Mathematics Computing Economy Behavior Science

  25. How Does Software Workshop Become Software Enterprise? • Improving Software Process • (1) What is the software process? • “The set of activities, methods, and practices used in the production and • evolution of software.” (SEI CMM (Humphrey, 1989, Paulk et al, 1993) • (2) A software workshop either without process or with incomplete process • (3) A software enterprise should have a standard and complete process. • (4) The process plays a central role in software business: Business Results Process Organization Management Skills Technology Process Process is the Glue.

  26. How Does Software Workshop Become Software Enterprise? • Improving Software Process • (5) Impact of SPI on product quality: SPI benefit report by Herbsleb et • al., 1994: • I. $490~2004 invested per software engineer per year • II. 9~67% annual increase in productivity • III. 15~23% annual reduction in cycle time • IV. 10~94% annual reduction in field error report • V. Return on investment ranging from 4:1 to 8.8:1 3+ 3+ Hi gh 2 Maturity Level Maturity Level Hi gh 2 2 2 Hi gh 1 Hi gh 1 1 1 0% 20% 40% 60% 80% 100% 0% 20% 40% 60% 80% 100% Process quality is ‘good’ or ‘excellent’ Ability to meet schedule is ‘good’ or ‘excellent’

  27. How Does Software Workshop Become Software Enterprise? • Adapt Advanced Software Management Standard • (1) ISO 9000/9001 – International Standards Organization (ISO)’s Quality • System Requirements which is not just for software, but can be used • for software system quality requirements standard. • (2) CMM – Capability Maturity Model which is the most well-known • software process improvement roadmap and which is the Software • Engineering Institute (SEI’)’s standard. • (3) TRILLUM Model – which has been developed by a consortium of • telecommunication companies, headed by Bell Canada. It is based on • the SEI’s CMM Version 1.1.

  28. Waves Of The Software Industry • The first wave was characterized by the waterfall lifecycle • and structured methods. The one of the most powerful features • the first wave gave us was the ability to represent software • activities diagrammatically. The step brought software • development nearer to becoming an engineering discipline. • The second wave is the process maturity movement which is • likely to push the software industry even further towards • becoming engineering discipline. • The third wave is expected to be software industrialization • where software development turns into a manufacturing and • assembly of components. • The software industry is currently in the midst of the process • maturity wave.
