Overview
• 85% of all software organizations are small
companies
• Less than 50 employees
• Not just a scaled-down version of large firms
• Different business goals
• Extremely responsive and flexible
• Flat structure
• Encourage entrepreneurship and innovation
• Focus on a specific market niche

Benefits of SPI
• Is software process improvement really
necessary in small software companies?
•
•
•
•
•
Greater software product quality
Decreased development risk
Increased competitiveness
Facilitation of marketing
Higher potential to export
4
Prominent SPI Models
• Well-known SPI standards not applicable to
small companies
• Difficult and bureaucratic
• Inadequate guidance and support
• Too costly for small enterprises
5
Competisoft
• A software process improvement and certification
framework developed by researchers and companies
from 11 Latin American countries plus Spain and
Portugal
6
Process Reference Model
• Specifically designed for small companies
• Contains guidelines and examples

Evaluation Model
• A set of measures for estimating the capability
and performance of software processes
• Capability measures
• Performance measures

Improvement Model
• A lightweight process for economically running
improvement programs in small organizations
• Iterative and incremental
• Composed of one or more improvement cycles
•
•
•
•
•
Initiating the cycle
Diagnosing the process
Formulating improvements
Executing improvements
Revising the cycle
Influenced by IDEAL
XP and Scrum

ISO 29110
• Published in 2010 by ISO
• A subset of ISO/IEC 12207 and MoProSoft
applicable to VSEs
• Tailored to fit VSE needs

ISO 29110 Guides
• Assessment Guide
• ISO/IEC 29110-3
• Management and Engineering Guide
• ISO/IEC 29110-5-1-2
• Single application, single project team
• Provides guidance on Project Management and
Software Implementation Processes

Deployment Packages
• Deployment Packages
• A set of artifacts facilitating the implementation of
a set of practices, of the selected framework, in a
VSE.

Summary
• SPI standards such as CMMI or ISO/IEC 15504
not suitable for small organizations
• Several research groups are developing SPI
models specifically designed for small
companies
• Most of these models are very new
• Evidence of success?
