The Fatal Flaw of Standard Costing
Standard costing looks flawless in a boardroom presentation. The concept is seductive: set standards, measure performance, analyze variances, and adjust. But on the factory floor, the implementation is often fundamentally flawed. By relying on historical data, delayed reporting, and siloed incentives, standard costing doesn't just hide operational waste—it actively encourages it.
In these days of real-time sensors and instantaneous telecommunications, traditional implementation of standard costing is an anachronism.
Setting of Standards
Standard Costing uses historical averages to set standards. That means all the (avoidable) factors that adversely affected historical performance are accepted as normal and built into the (high) standards to be achieved.
Example:
Company A has been using cheap raw materials
The cheap inputs resulted in high scrap incidence
Material usage has been historically high as a result
The material usage standard based on the historical average normalizes the high levels of scrap.
Better quality raw materials could have reduced scrap. But standard costing does not make this fact visible. It is also likely that the scrap reduction could reduce the total cost lower than what it is now. This big picture gets lost.
Result: The material usage standard leads to lower profits.
Comparing Performance with Standards
Performance has to be measured continuously to generate the data for comparison with standards.
Traditional measurement involves multiple stages: Recording in Travelers, manual transcription into paper records and a final data entry into the ERP. The reports comparing performance against standards and analyzing variations are available days later.
Result: Performance variance from standard is noticed much after the event.
Remedial Actions in a Changed Scenario
By the time the variance gets noticed by decision-makers and remedial actions are planned, the conditions could have changed.
For example, the machines from which the original data were generated could have worn out even more and the planned remedies could prove quite inadequate.
Result: Remedies are ineffective.
Favourable Variances Incentivize Damage
Let us look again at the cheap raw materials that caused higher scrap.
Standards are typically set for the price at which each material is purchased. If managers can get the material at a lower price, it is recorded as a win in the form of a "favourable" purchase price variance (PPV), and they get rewarded.
Result: A favourable PPV leads to an "unfavourable" impact on business profits.
The Cost Architect's View
An ideal solution will be to compute PPV based on Total Cost of Ownership (TCO) rather than the initial purchase price. TCO will consider the impact of using cheaper materials on the resultant levels of scrap incidence and on product quality.
For sustained results, organize to get real-time data to initiate remedial actions immediately. To make that possible, you need to observe what is happening now, what improvements are needed and implement a plan (with date deadlines) to make the improvements.
Organizing for Real-Time Data: Moving from the Ledger to the Floor
No amount of time staring at a spreadsheet will reveal the hidden operational friction draining your margins. Standard costing reports tell you that money was lost weeks ago; the shop floor tells you how it is being lost right now.
To become a Cost Architect, you must step away from the screen, walk the factory floor, and install real-time financial circuit breakers.
Identify the Hidden Leaks (What is happening now?)
Observe the physical reality behind the financial variances:
Do operations flow in a continuous line, or is there back-and-forth movement? Standard costing hides this wasted motion inside "standard labor hours," masking a massive loss of productive capacity.
When a machine problem emerges, how long does it take for that information to reach someone who can fix it? Every minute of delay is unrecoverable overhead.
Deploy Structural Fixes (What system improvements are practical?)
Shift your operational tools from being purely "lean initiatives" to active cost-control mechanisms:
Cell Manufacturing & Shadow Boards: By organizing workstations to minimize the physical movement of people and materials, you instantly reduce the hidden labor costs that standard models accept as "normal."
Andon Boards & Sensors: Standard costing reports an "efficiency variance" weeks after a machine fails. Andon boards and automated sensors provide real-time status reports, allowing you to stop the financial bleed the minute a problem emerges.
Empowering Operators: Authorize workers to shut down machines the moment they spot a defect. This prevents a $10 scrapped component from moving downstream and becoming a $100 failure in final assembly.
Localizing Maintenance: Station technicians directly on the shop floor to ensure equipment fixes happen before a single shift's profit margin is destroyed by downtime.
Execute the Architecture (Put improvements in place)
Do not wait for the end-of-month financial close to see if things have improved.
Draft a concrete project plan for these operational upgrades with strict deadlines.
Execute the plan and monitor the results on the floor daily.
Adjust your targets based on these new, structurally sound capabilities, rather than historical averages of past failures.
Conclusion
Standard Costing takes GIVEN as given. That means the deep-down issues that underlie many of the existing constraints and problems will not be attended to.
Standard Costing reports take weeks before they reach people who can take remedial actions. By the time they initiate the actions, the conditions on the factory floor could have changed much, making the actions inadequate or inappropriate.
You cannot manage costs from a spreadsheet; costs must be engineered on the shopfloor. Take a walk on the factory floor, observe what is happening, explore options for improvements, create actionable plans and execute them.
And monitor the results.
