The document describes Spago4Q, an open source platform for measuring, analyzing, and monitoring software quality, processes, and services. Spago4Q uses a meta model to define organizational structures, development methodologies, measurement frameworks, and assessment frameworks in a consistent and decoupled way. It collects data from tools through extract-transform-load processes into a data warehouse with a snowflake schema. Key performance indicators are then calculated and results can be viewed through reports and dashboards generated using the integrated SpagoBI business intelligence platform. Spago4Q provides a flexible yet standardized way to define, measure, and report on software quality metrics.

1. Open Source for Software Quality of
products, processes and services

2. Overview
The free/open source platform to measure, analyse
and monitor Quality of software products,
development processes and application services.
Spago4Q is a platform for the assessment of the maturity
and effectiveness of software development processes and
application services as well as for the quality inspection of
the released software. This goal is achieved by evaluating
data and measures, collected from the project management
and development tools through non-invasive techniques.

3. Goals
Highly adaptability to various organizational contexts
(imperativeness of the organizational procedures vs flexibility of the company environment)
Measurement processes not bound to the adopted software
development processes and tools
Automatic data collection from a set of tools
Support to a complex evaluation system
Measurement knowledge base: set of "library of measurements" and
model instances to satisfy the needs of the end-users, providing a
low-cost "out of the box" solution
Open system and compliance to the "de facto" standards

6. Meta Model
Key Concepts
Abstraction:
Meta-model adoption for all aspects of the process
measurement activity
Consistency between every single instantiated
measurement model and the abstract meta-model
Decoupling:
Software development tools
Data representation
Reporting framework
6

7. Meta Model
Spago4Q Meta Model defines:
The organizational structure (Company/Business Units/Projects)
The software development methodology (waterfall, evolutionary,
UP,SCRUM, etc)
Measurement framework (GQM model, etc)
Assessment framework (CMMi, ISO9001-2000, etc.)

8. Meta Model
Spago4Q Meta Model is compliant to
MOF (Meta Object Facility) standard

Spago4Q allows to:
define resources (projects, products, services)
define models (based on Goal Question Metrics or assessment framework
CMMI, ISO 9000-20008)
define KPIs and thresholds
create relationships between resources, models, KPIs and thresholds
define ETL processes and DWH data
extract information from measurement tools and load DWH
calculate KPIs
