Introduction to QA concepts

Grid-QCM focusProduct VS Process
Quality refers to several concepts like:
• Quality of the Implementation process
• Quality of the requirements management
• Quality of the service
• Quality of the software

TerminologyProduct VS Process
According to ISO 9126 documentation we can define:
• Measure: the number or category assigned to an attribute of an entity by making a measurement (sometimes used as synonymous of metric)
• Metric: The defined method to measure an attribute and the scale
• Measurement: The use of a metric to assign a value (which may be a number or category) from a scale to an attribute of an entity)

State of the ArtWe have tons of stuff in the SoA!
State of the art provides • Hundreds of metrics
• Approaches to define user’s own metrics
• Many standards to asses the quality of processes and products
So, what’s the matter?!?

The matterEffort and resources
QA means initial investments and
Managing QA means devote resources to it
Many companies (e.g. SMEs) cannot afford the initial effort and do not recognise the promised increase of value.
• Only ~70 companies in the world are CMMi lev.5 certified • 50 of them are in India
• source: Gartner
• Just 25% of the companies in the world are CMMi lev.2 or above • source: Kulik, Weber: “Software Metrics Best Practices – 2001”
and “Software Metrics State of the Art – 2000”

Current standards issuesWhy studying for one more QA certification model
Current quality assurance standards are useful but
• They need lot of time to be applied. • People need training
• Certification needs inspections to be achieved
• What for the short-lived consortia?
• They provide only theoretical guidelines which need to be adapted and implemented. What for homogeneity and comparability of results?
• It’s hard to systematically verify goodness of results: managing tools needed

Grid-Quality Certification ModelOur proposal to help developers
Grid-QCM is
• fully automatable in measuring and verifying activities to reduce investments and management effort
• not subjective, to certify the object not the process nor the organization
• product oriented, not process oriented
• easily adoptable within short-lived Projects

The structureEvaluation modules
Grid-QCM is structured in Evaluation Modules (EM).
The set of evaluation techniques are grouped in families. Every family is an Evaluation Module
5 Evaluation Modules:• Static analysis
• Coding style
• Structural testing
• Functional testing
• Standards compliance

Evaluation Modules 1/2
Static analysis• Quality characteristics:
• Reliability – maturity
• Maintainability – analysability
• Maintainability – changeability
• Maintainability – testability
• Static analysis of classes. Statistics on measures are used as predictor of quality characteristics.
Coding style• Quality characteristics:
• Maintainability – analysability
• Static analysis of the source code.

• A list of passed and failed tests
• All the important information as:• Software product
• Platform
• Quality characteristics
• Standard compliance
• Identification of evaluation report
• Identification of certification body (organization, contact information)
• Certification data (dates, certification number)
• Electronic signature of certification record

Some FAQs
23Grid-QCMAutomation in Quality Assurance
INFSOM-RI-1234567
Open Grid Forum 23Barcellona, 2° June 2008
Some Questions and Answers Yes, but…
What’s good about Grid-QCM for my project?• This model (and the capability of automation) reduces the effort
in performing continuous build and test activities (e.g. coverage tests) on different SW releases.
What are the costs?• Using the ETICS tool people can have the model integrated in
the build and test application free of charge
My organisation is certified ISO/CMMI can I use Grid-QCM?• The model is a standalone quality certification model.• However it can be easily integrated in yet ISO/CMMI certified
organisations.

It is not enough…What ETICS and Grid-QCM can do for ENG
…Some quality aspects are not covered
Grid-QCM + the ETICS suite • Measures other quality aspects such as:
• Quality of the code
• Compliance with standards
• Compliance with OS
• …
• Can be integrated with the Spago4Q suite
So, Engineering is managing the activities to make Grid-QCM + ETICS a tool to keep the CMMi lev.3 certification

Conclusions
29Grid-QCMAutomation in Quality Assurance
INFSOM-RI-1234567
Open Grid Forum 23Barcellona, 2° June 2008
Conclusions And further steps
Grid-QCM is a certification model• Automatable
• Implemented by default in the ETICS tool
• Ready to interact with classical standards
Adopting Grid-QCM requires little human effort
During the ETICS 2 project • Grid-QCM is going to be validated on-the-field with at first two
(Dec. ‘08) and then four projects (Dec. ’09)
• Grid-QCM will be proposed for the ISO standardisation (2009)
