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

Product Life CycleThe product life cycle consists of three phases: 1. Develop the product 2. Operate the product 3. Decommission the product

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







Initiation

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 informationProduct

InitiationProduct





FeasibilityFeasibility

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.

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

Testing Phase:

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






LaunchLaunch

Operation Phase:• Longest Phase

• Manage the product

• Track problems and bugs, and respond to customer issues

• RASM (Reliability, Availability, Security and Manageability)






OperationOperation

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

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

The Actual Product

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

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)– Integrated software solution designed to close the gap between idea capture and

comprehensive product lifecycle management

• Mystic Management Systems - ensurPLM (For All Businesses) – Tool for effectively managing the development of products from concept to design,

through production planning and marketing

• iRise - iRise Studio (For Enterprise Businesses) – Easy-to- use application definition solution used by business experts to quickly assemble

functionally rich simulations of Web-based applications

• PTC - Pro/ENGINEER Wildfire (For Enterprise Businesses)– Allows you to design faster than ever, while maximizing innovation and quality to

ultimately create industry-winning products
