Actual needs of (Hungarian) software developers • Software companies experience more and more the requirement of producing provably good - quality software, “certified software”, as a condition for staying in the market. Practical steps in using multiple quality models in a synergic way
Attributes ISO 9126 CC Metric GQM ISO 9001:2000 SPICE CMMI ISO 15504 Automotive SPICE TSP, PSP QA Def Objects Process Product Resource PM methodologies People CMM Actual needs of (Hungarian) software developers ? • What to certify • Product, process, resources… • According to what standard / model? • ISO 9001, AQAP, CMMI, A-SPICE, ISO 9126, CC… • How to get efficient results (from certification and SPI)? • Do SPI • by using more quality models ---- in a synergic way!!!!

The QMIM framework • Scope: give a solution to the problems mentioned before • Framework (not the n+1-th approach!) • Was developed during a case study • Helps identifying the important elements of software quality • Helps finding one’s way among the existing software quality models, standards, approaches • Supports software process improvement by following small steps Practical steps in using multiple quality models in a synergic way

Practical steps in using multiple quality models in a synergic way • Main goal: • Common vision of Q-issues • One QMS… • …containing all elements of Q, important at a certain moment for the company • …having „parts” compliant to the standards / approaches important at a certain moment for the company • …completed systematically with new elements / standards / approaches that become important for the company Practical steps in using multiple quality models in a synergic way

Practical steps in using multiple quality models in a synergic way • Develop a PM system! • Use elements of a PM methodology! (PRINCE, PMBOK, elements of RUP etc.) • Put in place an ISO 9001:2000 conform QMS! • Take into account ISO 90003:2004 recommendations! • X(Complete the QMS with elements from CMMI (DEV, ACQ and / or SVC)) • … • X(Complete the QMS with elements from Automotive SPICE) • … • X(Use ISO 9126 to define product quality attributes and metrics) • ISO 14598 , ISO 25000 • Define your product types • Use GQM for metrics! • ... Continue by using elements of further models, as business drives you!!! Practical steps in using multiple quality models in a synergic way
Practical steps in using multiple quality models in a synergic way • One example: • Completing and ISO 9001:2000-based QMS for CMMI compliance • (We assume that a PM system exists – possibly as part of the QMS) • Practical steps: • Understand and compare ISO 9001:2000 and CMMI • Both are process-oriented approaches… • Understand similarities and differences in scope, structure, terminology… • CMMI: what is the scope? (certain PA’s, certain CL’s, certain ML?) • Look to your business goals when defining scope! • Gap-analysis • Missing elements • SPI plan • Make sure you keep ISO 9001:2000 compliance!!!

ISO 9001 – CMMI: basic differences - examples Using results of Zádor Dániel Kelemen: Comparing ISO 9001:2000 to CMMI (2007) Practical steps in using multiple quality models in a synergic way
ISO 9001 requirements in CMMI Using results of SQI and Zádor Dániel Kelemen: Comparing ISO 9001:2000 to CMMI (2007) Practical steps in using multiple quality models in a synergic way
From ISO 9001 to CMMI Process capability profile according to CMMI found in 8 ISO 9001:2000-certified companies, where no previous CMMI-based SPI was conducted (IKKK-GVOP-2004-3.2.2) Practical steps in using multiple quality models in a synergic way
Some basic ideas Transform the way of doing Quality Management Continuous QM, phased to projects (already at ML2 / CL2) Product quality management (recommends ISO 9126) Measurement Make use of existing quality goals and metrics Build context-dependent quality profiles (eg. by product type) Use GQM (Goal-Question-Metric paradigm) Do continuous measurement for important quality attributes of products, processes, resources Do not forget: all PA’s need an attached measurement already at CL2! Moving from an ISO 9001-conform QMS towards CMMI Practical steps in using multiple quality models in a synergic way
Moving from an ISO 9001-conform QMS towards CMMI • Some basic ideas (cont.) • Define and implement „baselines” and configuration audits • Describe estimation and risk management process (first at project level) • Plan, monitor, control all PA’s in scope ! • Define a system to ensure bidirectional traceability of requirements! • ML/CL3: • Technical processes • Define technical processes (possibility: make use of product types defined – probably, each is connected to one technology!) • Standard processes and tailoring guidelines Practical steps in using multiple quality models in a synergic way

Conclusion • One vision for QM – one QMS! • Start by using the elements / standards / models important for your business! • Having QMIM framework in mind… • … the existing, solid QMS can be enhanced with new elements, required by the actual business goals • … there will be no (or very few) overlaps and redundancies Practical steps in using multiple quality models in a synergic way
