  1. The Practice of Deploying DSM Report from a Japanese Appliance Maker Trenches http://www.dsmforum.org/events/DSM06/ Laurent Safa

  2. Today’s Menu • Software Modeling at MEW • Tool & Scope • More Scope: HA Domain • DSM Challenges • Proposed Solutions • DSM and Cognitive Dimensions • Questionto the Workshop

  3. We see modeling and code generation as a way to significantly reduce human-factor in embedded software Practitioner Practitioner Tool maker Software Modeling at MEW Stop Human-Factor Safe Software Embedded application Modeling Tool use produce Model-driven Development Software Risk Embedded application write human factor Traditional development

  4. Tool & Scope App App App App Application Requirements Application Framework Framework Find solution Deploy solution Middleware Middleware OS OS Hardware Hardware New technology First-of-a-kind application Pass-over to Product Division Technical Creativity Problem solving Functional Creativity Solution variations Classic Software Engineering Software Process Improvement Domain-Specific Modeling

Total SoftwareProduction Cost Quality Assurance 50% Untapped Potentially Huge Savings 50% Application 15% SoftwareDevelopment 50% Framework 10% Middleware 20% BSP 5% More Scope: HA Domain Next DSM ?

  6. Practitioner Practitioner Tool maker DSM Challenges Many tools to maintain Embedded software Manylanguages to master Modeling Tool 3 Framework 3 Model-driven Developmentis Viscose New tool to use Modeling Tool 2 Embedded software Who’s the tool useranyway? Modeling Tool 1 Framework 2 New (expensive) practitioner Embedded software write “C” Traditional Environmentis Fluid What happens to me? Framework 1

  7. Practitioner Practitioner Tool maker Proposed Solutions Test-driven metamodeling Embedded software Family ofsimilar languages Modeling Tool 3 Framework 3 Model-driven Developmentis Viscose HCI Modeling Tool 2 Problem-based user selection Embedded software Modeling Tool 1 Framework 2 Configurablemetamodeling tool(DSM tool’s toolkit) Embedded software write “C” Traditional Environmentis Fluid Present DSM as a pain-killer Focus on creative developments Framework 1

  8. DSLs and Cognitive Dimensions http://www.cl.cam.ac.uk/~afb21/CognitiveDimensions/

  9. Question to the Workshop What are other approaches to • Foster usability • Sustain deployment • Reduce initial cost of DSM tools? Knowing • To foster usability we do escape semantics, convention over configuration, unknown, only-one-view DSL, default behaviors • To sustain deployment we do test-driven metamodeling • To Reduce initial cost we use a configurable modeling tool

  14. Full2Way Escape Semantics Union by: A. Tanaka (2006/01/25 16h30) With Full2Way, the address space from 0 to 255 is shared between “tu” and “dimmer” equipment. Each address within that space can be either bit or integer[0..127]. The selection can be changed at run-time by loading a new configuration file. tu : bit dimmer : integer [0..127] 256 Lightingequipment dimmer : integer [0..127] 16 127 group : bit pattern 72
