Software Product Development Process and Life Cycle

Dear Friends,

Internet is full of information with different and various information. The information may come in different forms.

I am true researcher and love to search about upcoming, happening, and new technology available for our generation.

This time, I saw very unique and new technology that is Slide Share. As we use Orkut, Facebook and other Social and Professional networking sites.

Slide Share is a online library of all the power point presentations, webinars that contains lot of content which is very valuable during this era of Information Technology.

I want to share this Software Product Life Cycle Prepared by: Mahesh Panchal Nitin Garg Ravindra Nath Sharma Utkarsh Khare.

Software Product Life Cycle

  1. Software Product Life Cycle
  2. Product Development
    • Product development is the process of:
      • designing
      • Building
      • Operating
      • maintaining a good or service
    • Not just manufacturing a technology, but creating a product that people will want to buy and continue to use. It adds:
      • Pricing
      • Marketing
      • Customer Support
    • Without a Product Management philosophy and discipline, IT organization becomes focused on the technology instead of the customers
  3. Product Life Cycle
    • The product life cycle consists of three phases:
    • Develop the product
    • Operate the product
    • Decommission the product

  1. Product Initiation Phase:
    • Submits a request for a new service or modification to an existing service.
    • Received and prioritized by the Program Management Office (PMO).
    • Requests are reviewed by various management
    • If approved, the request is given necessary funding and resources

  1. Feasibility Phase:
    • Idea is explored in more depth
    • Evaluate:
      • Evaluated at the engineering and product management level.
      • Evaluated for technical feasibility .
    • Outlines the general architecture of the proposed service.
    • The Feasibility Analysis and stable Business Case are also developed during this phase.
    • These documents summarize time and cost estimates and other investment information

  1. Design and Plan Phase:
    • The cross-functional team documents all detail pertaining to the development of the service.
    • Core documents:
      • Marketing Service Description, Technical Service Description, and Design Specifications, are stabilized.
      • Operations, QA, and Customer requirements
    • Approved :
      • Initial Level: signed off by the project team
      • Final Approval: The Design & Plan Checklist is presented to the Governing Committee.

  1. Development Phase:
    • Parameters to pass through decision gate:
    • Actual engineering of the service is completed
    • Code Complete
    • Documentation Complete
    • Ready for Testing Phase from a System Integration Test perspective
    • Test Environment Complete
    • Vendor Requirements met
    • Integration Testing & Results Complete
    • Approval by Project Team & the Governing Committee

  2. Product Launch Phase:
    • Flash demo and deploying it on the company website
    • Deployment of the new or modified service at customer end.
    • Initiation of support processes to maintain the service.
    • A predetermined un-launch process will be executed, If the service is found to be unsuccessful

  1. Operation Phase:
    • Longest Phase
    • Manage the product
    • Track problems and bugs, and respond to customer issues
    • RASM (Reliability, Availability, Security and Manageability)

  1. Decommissioning Phase:
    • End of the product life cycle
    • Decommissioning can be ignored
    • May lead to larger problems
    • Product is phased out from the Market
    • Example Windows 98
    • Example AVG 7 is being decommissioned on 1 April 2009
    • Extending the life cycle of Product

  1. Case: Introduction
    • About adobe Flex:
      • Adobe Flex is a collection of technologies released by Adobe Systems for the development and deployment of cross-platform rich Internet applications
    • Case briefing:
      • Dashboard application built jointly by Macromedia Strategic Services and WHITTMANHART, which uses the following dashboard application today to monitor their business
    • Problem
      • The executives spent too much time analyzing and processing their corporate data
      • Team: 11
      • Duration: 9 months
      • Product: Dashboard application for Business Use
  2. Adobe Flex: Product development Phases
  3. Team
  4. Roles within the life cycle of a Flex application
  5. The Actual Product
  6. Difference between the Software Product Life Cycle and the Software Development Life Cycle
    • In reality there is some overlap between the SPLC and the SDLC
  7. Tools
    • Digite - Digite Enterprise ( For Enterprise Businesses )
      • Solution incorporates a range of tools, content and processes to successfully convert business requirements to IT solutions
    • UGS PLM Solutions - TeamCenter ( For Enterprise Businesses )
