o v o

• Data, information, and knowledge are valuable assets forbetter organizational decision making.

–Data, information coming from M&EData, information coming from M&E• To Measurement, Evaluation & Analysis processes for QA,an integrated M&E strategy is necessary.•To assure repeatability and consistency of results amongprojects, we argue the following three aspects of a M&Estrategy should considered at once:strategy should considered at once:

– a measurement and evaluation process– a conceptual framework that relies on an a conceptual base

• such as an ontology–evaluation methods and tools instantiated from both the frameworkand process.

Motivationo v o

In previous works, we have built:– a framework called C-INCAMI (Contextual-Information Need,C d l A b M d I d ) b d iConcept model, Attribute, Metric and Indicator), based on a metricsand indicators ontology; and– the WebQEM (Web Quality Evaluation Methodology) method andits associated tool (C-INCAMI Tool)

I hi k if i li i d f l hIn this work, we specify, in an explicit and formal way, theM&E process, based on:

– the terminology used in the ontology and the C-INCAMI components,gy gy p ,and– the WebQEM underlying activities– ISO processes.p

Motivationo v o

Some related works (stressing the process aspect):

• SQuaRE (Software product Quality Requirements and Evaluation)–ISO 15939: Software Measurement ProcessISO 14598 5: Process for evaluators–ISO 14598-5: Process for evaluators

• CMMI (Capability Maturity Model Integration)– Measurement and Analysis PAy– Decision Analysis and Resolution PA

C-INCAMI Framework

C INCAMI provides a domain (ontological) model defining allC-INCAMI provides a domain (ontological) model defining allthe concepts and relationships needed to design and implementM&E processes.M&E processes.

The C-INCAMI framework is structured in six components(packages) namely:(packages), namely:1. M&E project definition2. Nonfunctional requirements specification2. Nonfunctional requirements specification3. Context specification4. Measurement design and implementation5 Evaluation design and implementation5. Evaluation design and implementation6.

M&E Process

A process prescribes (or informs) a set of phases and activities, inputsand outputs, roles, among other concerns, in order to fosterrepeatability and reproducibility.

Gi th i h t l it f th d iGiven the inherent complexity of the process domain, a process canbe modeled taking into account different views, namely:

• Functional• Behavioral•Informational•Organizational

M&E Process

Taking into account the C-INCAMI framework and tosome extent the ISO standards for M&E, our integratedprocess proposal embraces the following main (core)process proposal embraces the following main (core)activities:
