6. KEY FACTORS OF SAAS ENABLEMENT
Factor Considerations
oUnderstand business objectives, including licensing model
Business and project planning oAssessment of current product and skills needed
oIncremental project plan or new product development
oSupport for multi-tenancy
Architectural Planning oScalability and manageability considerations
oTechnical approach and use of current product

7. WHY AGILE WORKS FOR SAAS DEVELOPMENT
New and
CorSource
New Product Changing
Software
(SaaS) Requirements
Development
• New business model • Not fully known at start • Predictable schedule
• New interaction model • Need to involve clients • Incremental dev
• New features • Need to evolve over time • Short iterations
• Working iterations
• Quick evolution
Agile methodologies foster product evolution during
development resulting in products that better meet
customer requirements.
8. KEY BENEFITS OF AGILE METHODOLOGIES
Key Characteristic Key Benefits
Predictable Delivery o Can predict product delivery with more accuracy
Schedule
Flexible requirements o More rapid response to changing requirements over time
Iterative – incremental o Allows business and technology to stay in sync
development o Able to maintain a sustainable rate of development
Continuously working o Development and testing in sync at all times
software o Few quality issues at end of full development
o Can demo and get feedback continuously
Team orientation o Gain understanding and buy-in of full team, including
customers in many cases
o Monitor and improve team performance over time

14. PRIMARY TECHNOLOGY CHOICES
Selected
Area Rationale
Technology
Application Microsoft .NET Company X has current skills and foundational
Architecture architecture. Other option is Java, which provides no
significant advantages.
GUI Platform Microsoft Aligns best with .NET. Scripting / rapid development
ASP.NET choices such as PHP or Ruby on Rails do not provide
the robustness and flexibility required of enterprise
software.
Database Microsoft SQL Company X has current skills and foundational
Management Server architecture. SQL Server 2005 has reached par with
System Oracle, DB2, and open source alternatives (e.g. MySQL)
for all but the highest transaction loads.
