4. 4 Agenda Modeling and Methods What is a Software Factory? A Software Factory Schema Domain Specific Languages Wrap Up

5. 5 You all know what modeling is…

6. 6 Spend a lot of time drawing loads of these…

7. 7..throw them away and get on with the code But wait! Isn’t the code also a model? So what exactly do we mean by “model”? Using Microsoft.Fabriq. EnterpriseInstrumentation.Schema; namespace Microsoft.Fabriq.Util { /// /// This class provides unified /// management, eventing, … /// public class Logger { public static void LogErrorMessage( string message, int severity, string errorCode) { ErrorMessageEvent.Raise( FabriqEvents.FabriqEventSource, message, severity, errorCode ); }

8. 8 Are our models “mathematical models”?

9. 9 Are they “scale models”?

10. 10 Are they “theoretical models”?

11. 11 Definitely not this kind of model… Copyright: www.gucci.com

12. 12 A software “model” is Partly about visualisation  Abstraction for clarity  Because picture worth a thousand words Sometimes about algorithms  Expression in a convenient form  Because compact and efficient Often a set of instructions  A recipe  Because can be automated

13. 13 You all know there is a “method in the madness” of software development…

14. 14

15. 15

16. 16 A software “method” is A way of working from requirements to through implementation to deployment Typically process-oriented  Identifying a set of artifacts  Building those artifacts  Producing deliverables

17. 17 Customers Want To Know What types of systems can I build?  What’s the architecture of each type? How do I go from requirements to deployment?  What artifacts and how are they related? Why are methodologies so ineffective?  Why aren’t they integrated with my tools?  Why can’t I get detailed and specific guidance for my project? Why are modeling tools so ineffective?  Why can’t they generate production quality code?  Why don’t models stay synchronized with code?  Why can’t models fit my file-oriented environment?

18. 18 Is Agility The Answer? Agile methods optimize for change  Collaborating instead of documenting  Building and running in small iterations  Continuously validating requirements  Continuously refactoring the software  Time boxing or cash boxing the project Where do they fall short?  Don’t scale up to large or complex projects  One-off development of generic systems  Lack of metadata limits degree of automation  Lack of architecture documentation creates integration and support issues

19. 19 Is Formality the Answer? Formal methods optimize for complexity  Prescribing roles, artifact, activities  Emphasizing requirements, analysis, design  Using models to document architecture Where do they fall short?  Don’t respond rapidly to change  One-off development of generic systems  Coding, testing, debugging, instrumentation, deployment, management, maintenance  Informal languages and mappings limit degree of automation

20. 20 Agenda Modeling and Methods What is a Software Factory? A Software Factory Schema Domain Specific Languages Wrap Up

21. 21 Software Development as Craftsmanship Labor Intensive Generic Tools Generic Processes One off applications Hand stitched from scratch Minimal reuse Overruns, defects, security holes, project failures

22. 22 Exploiting Commonality We already exploit economies of scale to automate production Stamping out many identical copies of a prototype Used to produce CDs/DVDs Does nothing to help development

23. 23 Exploiting Commonality We can also exploit economies of scope Reuse designs & components Build many similar but distinct prototypes Key is supporting variability Define only the unique pieces of each system

24. 24 Software Factories Domain-specific process Domain-specific tools & languages Domain-specific content Automate rote and menial tasks General-purpose IDEs become domain-specific software factories

25. 25 Software Factories Pillars – TBC Warning: This is a personal perspective Process, Tools & Languages, Content, Automation Software Factories Visual Studio (Whidbey, Orcas) DSL Tools GAT “FALCON” GAT SDM SDK? MSF Process Agile / Formal Trustworthy Metadata Rich Platform
