Vision Ingredients of a Software Factory Implementation How to create artifacts for a Software Factory Creating a guidance package Defining a DSL This Session Is About

Factory Ingredients Patterns Provide general solutions to common problems Frameworks Provide supporting and reusable assets Concrete e.g..NET Fx Abstract e.g. Zachman Framework Models Provide a formal way to describe a specific problem Are able to execute or produce formal artifacts Methodologies Define a codified set of recommended practices Tools Support creating, maintaining and debugging

How to build a Software Factory Vision Vision

Inception Identify example solutions Use them to elicit requirements Use them to validate factory Determine what you have to work with Do you have any existing assets? What are the constraints on the solutions you build? Required technologies, preferred vendors What are the constraints on how you build them? Existing development process conventions Approval by an internal architectural review board Safety critical certification from a third party

Construction (iterative) Identify experience to be harvested Common solution elements Requirements, architecture, feature groups, components and subsystems, deployment topology, development process, cross cutting aspects Viewpoints, relationships and operations Artifacts and activities in each viewpoint Develop assets to describe and support activities Domain assets like specifications from standards bodies Design assets like styles, patterns or idioms Implementation assets like class libraries, frameworks, templates, wizards, tools Separate common and variable features Map feature variations onto variability points Package and deliver the assets

Refine Along Three Dimensions Coverage Start with a small kernel and prove its value (UIP) Grow to address more of the problem (Service Access) Generality Start with a constrained problem domain (caching) Grow by adding variability (pluggable key algorithm) Depth Start telling them what to do (UIP guide) Grow by doing more for them (UIP block, UIP designer)

How it was built DSL for UIP DSL for UIP

Assets for the UIP DSL Patterns MVC (in UIP) Frameworks UIP Windows Forms Tools DSL Toolkit Property Editor

Approach for building DSL Defining the requirements and the abstractions Pattern languages vs. domain languages The syntax Transformations Moving down the abstraction layers

UIP Starting Point Manual development of Controller View to Controller binding Configuration file

Controller implements Page Flow

Views "offer" their State

Views call the Controller

Configuration Defines Flow

Defining the Abstract Syntax

Defining the Concrete Syntax

Transformations Configuration File Controller Page classes Wizard-related page classes

Creating a DSL from scratch...

Identifying the Product Product families and product lines Generic, similar and individual features

Designing a Language User Focused Start with the concrete syntax User in mind Grammar Focused Start with domain model and abstract syntax Templating in mind

Grammar Focused

User Focused (Use Case)

How Can You Start Today? Designing frameworks? Think about a custom language for your framework How would it look like? Does it simplify the use of your framework? Does it reduce the training effort?

Technical Issues Today Even if the DSL tools are not yet released Determine that your framework's architecture supports DSLs How could you generate code (partial classes, config files,...)? Which parts are cumbersome, where do you need support? How will developers use the DSL?
