SaaS Maturity Levels
Level 0
• Outsourcing is not SaaS. In outsourcing, a service provider operates a major application or a unique application landscape for a large enterprise customer. As the outsourcing company can't leverage this application for a second customer, outsourcing does not qualify as SaaS.
Level 1
• Manual ASP business models target midsize companies. At level 1, a hosting provider runs packaged applications like SAP's ERP 6.0, which require significant IT skills, for multiple midsize enterprises. Usually, each client has a dedicated server running its instance of the application and is able to customize the installation in the same way as self-hosted applications.
Level 2
• Level 2: Industrial ASPs cut the operating costs of packaged applications to a minimum. At level 2, an ASP uses sophisticated IT management software to provide identical software packages with customer-specific configurations to many SMB customers. However, the software package is still the same software that was originally created for self-hosted deployment.
SaaS Maturity Levels
Level 3
• Level 3: Single-app SaaS is an alternative to traditional packaged applications. At level 3, software vendors create new generations of business applications that have SaaS capabilities built in. Web-based user interface (UI) concepts and the ability to serve a huge number of tenants with one, scaleable infrastructure are typical characteristics. Customization is restricted to configuration. Single-app SaaS adoption thus focuses on SMBs. Salesforce.com's CRM application initially entered the market at this level.
Level 4
• Business-domain SaaS provides all the applications for an entire business domain. At level 4, an advanced SaaS vendor provides not only a well-defined business application but also a platform for additional business logic. This complements the original single application of the previous level with third-party packaged SaaS solutions and even custom extensions. The model even satisfies the requirements of large enterprises, which can migrate a complete business domain like "customer care" toward SaaS.
Level 5
• Dynamic Business Apps-as-a-service is the visionary target. Forrester's Dynamic Business Application imperative embraces a new paradigm of application development: "design for people, build for change." At level 5, advanced SaaS vendors coming from level 4 will provide a comprehensive application and integration platform on demand, which they will prepopulate with business applications or business services. They can compose tenant-specific and even user-specific business applications on various levels. The resulting process agility will attract everyone, including large enterprise customers.

Advantage Multi-Instance Efficiency gains — Virtualization allows to deliver efficiencies much closer to
multi tenancy by allowing for rapid and even automated creation of complete and identical new Virtual environments, full backups/snapshots of environments, easy upgrades across multiple environments, automated load balancing, etc.
Avoiding downsides, achieving delivery advantages — clients have a need for system changes to match key cycles — like their pay for
performance cycles. As a result, there is a demand for more tightly controlled, client-unique system changes.
concerns over: ▪ (a) security and inappropriate data access, ▪ (b) impact of other clients on their system performance, ▪ (c) inability to establish and pay for their own, higher service levels (common
among large companies), ▪ (d) being forced into an upgrade, ▪ (e) inability to support the level of client specific configurations and even
customizations as necessary, ▪ (f) inability to obtain client level user acceptance testing, ▪ (g) inability to determine the precise production/go live dates for the system.
