Setting Standard Costs

• Accountants, engineers, personnel
  administrators, and production managers combine
  efforts to set standards based on experience and
  expectations.

I agree. Ideal standards, based on
perfection,are unattainable anddiscourage

Note

• The argument that ideal standards are
  discouraging has been persuasive for many years.
  So normal defects and waste were built into the
  standards.
• In recent years, TQM and other initiatives have
  sought to eliminate all defects and waste.
• Ideal standards, that allow for no waste, have
  become more popular.
• The emphasis is on improvement over time, not
  attaining the ideal standards right now.

Variance Analysis and Management by Exception
How do I know which variances to investigate?
63
Advantages of Standard Costs
Management byexception
Possible reductionsin production costs
Simplify Bookkeeping
Responsibility Accounting
Improved cost control and performanceevaluation
Better Informationfor planning anddecision
making
64
Disadvantages ofStandard Costs
Emphasis onnegative mayimpact morale.
Favorable variancesmay bemisinterpreted.
PotentialProblems
Continuous improvementmay be moreimportant
thanmeeting standards.
Standard costreports maynot be timely.
Emphasizing standardsmay exclude otherimportant
objectives.
Incentives to build Inventories, to absorb excess
overhead

Delivery Performance Measures

• Delivery time cycle time from when an order is
  received from a customer to when it is shipped
• Manufacturing cycle time (throughput time) time
  required to turn raw materials into completed
  products
• Objective is to reduce/eliminate non-value added
  activities such as waiting, inspection, move,
  rework, test and queue time
