Question 36

What are the criticisms of using standard costing in the modern business environment?

Answer 36

1. Fast changing customer needs require flexibility 2. Not suitable for JIT where high quality is required 3. Total Quality Management calls for continuous improvement, which needs ever evolving standards 4. Attainable standards would need to allow for wastage/idle time and is at odds with quality principles 5. Labour is now a much smaller portion and tends to be fixed in the short term
