Excellence in New Product Development

Wireless Open-Source / Open-Architecture Command and Control

System (WOCCS) Roadmap Presentation

Leadership New Product Development (NPD)Set Based Concurrent Engineering (SBCE)

• Course Objectives: Leadership in NPDLearn/Apply principles of effective leadership to

product development issuesUnderstand best practices in the management of

product strategy/developmentIdentify general “failure modes” of task oriented

teams, anticipate and prevent potential problems.

• Course Objectives: SBCEUnderstand basic concepts of lean production

systemsReview emerging best practices in lean NPD and

SBCEDemonstrate “leadership from below”Develop a roadmap for future technology

researchImprove product development/innovation skills

Traditional Point Based Approach

• Attempt to rigidly define solution at beginning of development.

• Serial approach with defined stages.• “20 questions” without feedback

Is it a animal, vegetable or mineral? AnimalIs it a muskrat? NoIs it a goldfish? NoIs it a lion? NoIs it a bird? NoIs it a crocodile? Yes

• A point is picked and tested.  Open loop with no feedback from previous efforts.

Set Based Concurrent Approach

• End solution is initially undefined, multiple concurrent solutions are pursued simultaneously.

• Iterative approaches yield progressively more information

• Interfaces are defined early to permit concurrent development of discrete components.

• Benefits:Decisions can be deferred until later Risk can be more easily managed by trying

multiple approaches which are simultaneously explored

Design converges more quickly versus point based approach

Example of Set Based Concurrent Development• Power supply

Initial design: 70% efficient, ship date 6 months2nd design: 80% efficient, ship date 12 months3rd design: 85% efficient, ship date 24 months

• All three options concurrently pursued Guaranteed shippable product in 6 monthsIf 2nd design is ahead of schedule, it may be

incorporated into the first design in lieu of the first proposal.

Second and third iterations will be 'ready to go' for the next iteration of the product.

 

Wireless Open-Source/Open-Architecture Command and Control System

(WOCCS)

• Technology based on open hardware/software architecture Communication backbone for multiple vehicles (air, land, sea)

controlling motion, collecting and retrieving data• Develop future Harris talent

Engage up to 36 RIT engineering students annually Exposure to complex embedded systems/environments Provide a talent base for future Harris RF needs Mirror Software Defined Radio (SDR) architecture used extensively by

Harris• Advanced Development

Provide a basis for future technological advances in design/development of communication products

• Continues the strong relationship between R.I.T. and Harris
