Motorola Process Improvement

• Tim Preuss Stacy Zalesak

2
Methods

• Periodic Prototyping
• Accelerated Life Testing
• Preventative Maintenance
• Computer Integrated Manufacturing
• Material Control System

3
Periodic Prototyping

• Definition - a specific method of scheduling and
  learning from prototype testing
• Series of relatively short duration learning
  loops
• Early in the development process.
• Focus on components and sub-system
• Strictly adhere to schedule play catch-up if
  need be
• Creates a tie between the goals of individuals
  engaged in engineering development and the goals
  of project managers

4
Accelerated Life Testing

• Definition - where components of a product are
  operated at high stresses and failure data is
  observed
• Goals Of ALT
• - To study how failure is accelerated by stress
  and fit an acceleration model to data from
  multiple stress cells
• - To obtain enough failure data at high stress
  to accurately project product lifespan

5
Preventative Maintenance

• Definition - planned maintenance of plant
  equipment that is designed to improve equipment
  life and avoid any unplanned maintenance activity
• Benefits
• - Reduced production downtime, resulting in
  fewer machine breakdown
• - Better conservation of assets and increased
  life expectancy of assets
• Beware of faulty maintenance and repairs

6
Computer Integrated Manufacturing

• Definition - The use of computing and
  communications hardware and software to plan,
  co-ordinate, monitor and control the totality of
  manufacturing activities within a firm.
• Tools
• FMS-Flexible Manufacturing System
• MCS-Material Control System
• CAD-Computer aided Design
• CAM-Computer Aided Manufacturing

Traditional vs. Technological

• Traditional
• Requires skilled works who can adapt to new
  circumstances
• More labor needed to perform simple tasks
• Quality inspection

• CIM
• Unskilled workers may be used since the criteria
  for there job (overseeing machinery) never
  changes
• Tasks can be automated to reduce the amount of
  labor for a task
• Uniform production
