  • Not to be covered – previously covered!!
    • Conceptual Design and Development
    • Systems Design
    • Production and Construction
  • What to cover in this meeting?
    • Utilization and Support
      • You are building this product and are going to deploy it. How do you support it (keep it running)?
    • Retirement and Disposal
      • When is this phase in its operational (service) life?
      • How are your firm, or the buyer, going to get rid of it?
utilization phases
Commercial Concept

Install Phase

Operation & Support Phase

Utilization Phases
support analysis
SUPPORT ANALYSIS
  • Fielded System
    • How to support the system?
      • Leave It on the Loading Dock and Forget It?
      • Have the Customer Mail it Back When It Fails?
      • Have a Field Crew do Repairs? Whose Field Crew?
    • How much will support cost for the life of the system?
      • This Will Determine How You Support the System
      • This Will Also Determine Who Will Pay for Support

post sale time stages of systems
Post-Sale Time Stages of Systems
  • Distribution/Installation and Initial Use
    • Shipment, setup, construction/installation, test, acceptance
  • System & Equipment Customer Support (post-installation, continuing thru Service Life)
    • This is where you find out if your repair analysis and cost estimates were correct
  • System & Equipment phase-out and Disposition
    • This is governed by the initial support analyses made during design. This cost may make or break a program
initial distribution customer support
Initial Distribution & Customer Support
  • Distribution and Customer Support –
    • Physical supply and distribution• Role of distribution• Material management, packaging, transportation, warehousing and handling
customer support post sale
Customer Support (post-sale)
  • Customer support (post-installation)
  • Maintenance and repair
  • Field engineering and data; feedback & use
  • System Configuration Management
    • Configuration Identification & Control Plans
      • Hardware, Software, Firmware
    • Configuration Status Accounting, Authentication
    • Configuration Mgmt Performance Metrics
  • Ongoing engineering change insertion
  • Minor Upgrades (components)
  • Major Upgrades (system)
lcc operations cost categories
operator labor,

repair labor,

support equipment maintenance,

recurring training,

repair parts and materials,

repair consumables,

condemnation spares,

technical data revisions,

transportation,

recurring facilities,

recurring item management,

software maintenance contractor services,

engineering changes, and

recurring warranties.

LCC Operations Cost Categories
operational field data
Operational/Field Data
  • Operational Use Factors Are Significant
    • We must know if a product is being used within the parameters for which it was designed
  • Service Can & Must Be Managed
    • To be cost effective
  • System Service Life Is Generally Long
    • And in these times getting longer
  • Maintenance Can Be Analyzed & Modeled
    • This is an on going process for the life of the product
operational field data cont d
Operational/Field Data (cont’d)
  • Life Cycle Costs >>
    • LCC Can Be Calculated with empirical info
      • This info can be used on future products as well as for upgrades on the presently fielded product
    • LCC of Design Options Can Be Compared
      • See if the option we used was the best
    • Minimum LCC Option is Preferred
      • Always

  • What is CASA?
  • The Cost Analysis Strategy Assessment (CASA) model is a Life Cycle Cost (LCC)/Total Ownership Cost (TOC) decision support tool. CASA can present the total cost of ownership depending on user selections: including cost of RDT&E, acquisition/production, operating/support, and disposal. CASA covers the entire life of the system, from its initial research costs to those associated with yearly maintenance, as well as spares, training costs, and other expenses.
  • CASA uses standard LCC/TOC and logistics equations for the computation of costs and resource requirements. CASA also enables optimization of spares allocation to be performed.
