  8. 8. Service Factory: What is the Problem to Solve? IT Solution Delivery Issues Quality Cycle time Risk Inconsistency of approach Across teams (skills) Semantics Delivery technology Methods Lack of reuse of implementation and process assets Architectural mismatch Ad hoc / program focused reuse Solutions Development projects do not have budget, charter or business scope to deliver shared services8 V1.0 052012 © 2012 Everware-CBDI Inc
  9. 9. Service Factory: Concepts & Drivers Purpose Execute repeatable process to produce shared services in efficient manner Specialization of Software Factory Manufacturing analogy Assembly from components Automation of standardized, repeatable processes Mass customization Produces families of products Factory Components Skilled workers with diverse roles Automated tools for design, construction and coordination Engineered processes, techniques and materials9 V1.0 052012 © 2012 Everware-CBDI Inc
  10. 10. Service Factory Systematic approach to reuse Implementation Assets – tools, design patterns, frameworks Process assets – test cases, harnesses, design methods Production assets – software artifacts providing ROI through reuse Highly automated service software development Building families of similar software service products Assembling self describing service components Developing DSL and tools using language definition, code generation, tool development technologies – massive reduction in handwritten code Massive scalability Larger projects Geographical, Sector distribution Extended product life cycles without loss of agility10 V1.0 052012 © 2012 Everware-CBDI Inc
  11. 11. Service Factory Fundamentals Frameworks Bootstrap implementations of services Based on common architectural styles Language based tools Support development of services Adapting, configuring and assembling framework based components Using tools to engage customers Respond to changes in requirements rapidly Building software services incrementally Capturing design decisions in a form that directly produces executables Brings all skillsets, disciplines, tools together in a single organization Centralized funding11 V1.0 052012 © 2012 Everware-CBDI Inc

  16. 16. Software Product Line Principles A software product line is a set of software-intensive systems sharing a common, managed set of features that satisfy the specific needs of a particular market segment or mission and that are developed from a common set of core assets in a prescribed way. -- Software Engineering Institute Strategic & systematic reuse Goal is to manage the product line, rather than products individually Configuration management becomes critical Commonality and Variability16 V1.0 052012 © 2012 Everware-CBDI Inc
  17. 17. Software Product Lines: Commonality & Variation within a Product Family Commonality Implement common service behavior patterns as reusable components Raise level of abstraction of reuse Architect for Variability Deliver policy driven service architecture Specialize family reference architecture to separate the aspects of the service that change at different rates Prediction Deliver generalized service components for family that are designed to be configured to create variants Exploit the Predicted Changes Standard infrastructure Platform for service reuse – SDK, SLA plus related processes Upgradeable designs and components17 V1.0 052012 © 2012 Everware-CBDI Inc

  23. 23. Model-Driven Development (MDD) Provides Accelerators Software delivery approach where specification models and other abstract artifacts are created to describe the structure and behavior of a system or module. Models are either executed directly or transformed into implementation code or environment control.
