Software Factories
• Help you build a specific kind of application
(smart client, service, etc)
• Incorporate a variety of guidance content types
and form factors
– Readable/Printable: Architecture guidance,
patterns, instructions, etc.
– Executable: Reference implementations
– Reusable: Application blocks
– Actionable: Guidance packages
• Encourage a process
Guidance Packages
• Open
– Documentation describes manual and
automated tasks
– Result of the automation is exposed
• Configurable
– Key configuration settings can be
captured within Visual Studio
– Automated guidance is defined
using XML
• Extensible
– Guidance can be tailored to meet
specific requirements
• Verifiable
– Generated code can be verified for
compliance within a standard
•
Additive Guidance
• Industry
• Microsoft
• Patterns &
Practices
• Organization
• Solution
Modifying a Guidance Package
• Types of modifications
– Level 1: Common and not many resources
• Guided using a recipe
– Level 2: Less common and more resources
• Code template and XML changes
– Level 3: Least common and most resources
• Requires an understanding of the GAX framework
• Helpful exercise in hands-on lab
• Nature of modifications
– Horizontal factory
Vertical factory
Helping Communication
Architect
Developer
Two Collaboration Scenarios
• Architects modify the guidance packages
– Encode organization and solution-specific guidance
– Developers use recipes to complete solution
– Architects validate the solution
• Architects use recipes to baseline
– Encode organization and solution-specific guidance
– Developers complete solution from the baseline
– Architects validate the solution

The Service Factory In Action
A Scenario for how Boeing might use it
for Supply Chain Management
• Service Design
• Security Patterns
• Code Analysis Validation
Boeing Supply Chain Management
• MaterialMgmtService

the ERP system
• Parts for engineering planes
are all over the enterprise
• This service aggregates onhand levels across all systems
• VendorGatewayService
• All vendors have
implemented a specific
contract
• This service manages calls to
specific vendors
