Systems and software quality

Software and systems quality is playing an increasingly important role in the growth of almost all ─ profit and non-profit ─ organisations. Quality is vital to the success of enterprises in their markets. Most small trade and repair businesses use software systems in their administration and marketing processes. Every doctor’s surgery is managing its patients using software. Banking is no longer conceivable without software. Aircraft, trucks and cars use more and more software to handle their increasingly complex technical systems. Innovation, competition and cost pressure are always present in on-going business decisions. The question facing all these organisations is how to achieve the right quality of their software-based systems and products; how to get the required level of quality, a level that the market will reward, a level that mitigates the organisation’s risks and a level that the organisation is willing to pay for. Although a number of good practices are in place, thereis still room for huge improvements. Thus, let us take a look into the two worlds of “Embedded systems” and “ICT systems” and let us learn from both worlds, from overlaps and individual solutions. The next step for industrialisation in the software industry is required now. Hence, three pillars will be focused in this book: (1) a fundamental notion of right software and systems quality (RiSSQ); (2) portfolio management, quality governance, quality management, and quality engineering as holistic approach over the three layers of an enterprise, i. e. strategic, tactical, and operational layer; and (3) an industrialisation framework for implementing our approach.
