SaaS
SaaS is the delivery of software applications over a hosted platform accessed through the Internet using a web browser and typically priced on a pay-as-you-go basis.

Business Facts
By 2010, 20% of companies deploying e-commerce will use a SaaS delivery model.By 2010, 15% of large companies will have started projects to replace their ERP backbone (financials, human capital management and procurement) with SaaS-based solutions.By 2011, 25% of new business software will be delivered as software as a service.By 2012, business process management suites (BPMSs) will be embedded in at least 40% of all new SaaS offerings.By 2012, more than 66% of independent software vendors (ISVs) will offer some of their applications optionally or exclusively as SaaS.IDC reports that it expects customer spend on SaaS to increase to $14.8 billion by 2011.Two out of three businesses are either buying or considering buying software via the subscription model.McKinsey reports that the proportion of CIOs considering adoption of SaaS applications in the coming year has gone from 38% a year to 61%.

SaaS Platform
Multitenant. Architecture should support for multiple tenant client.Single version. Applications offered as services are shared for all clientsLogical data separation. Each application has a domain data but in the same scheme. Multi-supplier. Multiple SaaS vendors can deploy their application.Domain container. Conceptual form to evolve applications’ supplier within the platform. The proposal is a customizable portal as access point.Application integration. Application should be able to communicate with each other.

Software Usage
Software Maintenance
- Requirements gathering from business model- Application design
- Develop, test and verifies a SaaS delivered application
- Platform provides API’s and tools
- SLA and operational parameters- Verify compliancy to platform policies- Install application over platform
- Customers discover the application- Customer learns about application- Customer tries and buys the application service- Aggregator bundles application with others
- Customer uses the application- Application customization- Platform monitors and manages the application- Platform reports and escalates incidents
- Application upgrade- Application patches

SaaS Requirements and Analysis
RequirementsDefinition of business plan requirements. Business plan that will require information from the application or platform must be identified.
Analysis of intended market. Outline and catalog the core needs of the target market. The product manager must assess the customer needs and focus in delivering the most value with the existing resources, a categorization of the application features could be used.
Definition of application features. Outline the main characteristics of the application service. These characteristics must be completely driven by the market and not by the software vendor.
AnalysisBusiness process analysis. Complex software cannot be based on people; it must be based on processes and automation
Develop use cases. Common use case documenting and modeling.

Conclusions
New service delivery platforms will become an important channel for software distribution in the near future.
The differences between developing software to be delivered as a good and to be delivered as a service are evident.
Considerations for every phase of the development of software to be delivered as a service.
