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 oFlexible processes for requirements, change management, Development and service process development and testing restructuring oAdopt agile methodology for development oCustomer service model oAll or subset of current product features Well-articulated requirements oModernization of user Interface oAdditional features required oMore flexible and maintainable Infrastructure Infrastructure migration oBalance resources between existing product and SaaS Existing product support enablement-how?
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.
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

PRIMARY TECHNOLOGY CHOICES Selected Area Rationale TechnologyApplication Microsoft .NET Company X has current skills and foundationalArchitecture 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 foundationalManagement Server architecture. SQL Server 2005 has reached par withSystem Oracle, DB2, and open source alternatives (e.g. MySQL) for all but the highest transaction loads.

FIVE PHASES TO SAAS – RETAIL SOFTWARE COMPANY o Applic. is multi-tenant-aware o Functional enhancements 1. Web Enable o Partitionable UI o Separate DB for each tenant (in a single DB instance)o Web UI (ASP.NET) o Load testingo UI enhancementso Light services layer (WCF) 2. SaaS Launcho Use current Delphi BOs/DAOs o Multi-tenant DBo Customizability (forms designer, plug-ins, …) o Tenant-aware admin toolo Data integrations (e.g. offline POS) o Migration toolo Migrate Crystal to the Web o Functional enhancementso Include SharePoint Services 3. True SaaSo Still set up by Prof. Svcs. incremental deployment as needed 4. Complete Technology Migration o .NET Business Objects o .NET Data Access Objects o Optional phase o Complete services set (plus refactored object o Refactor DAOs model, SPROCS, updated UI, etc.) o Active Directory 5.
