Savings from Work Standardization are often discussed, but rarely calculated in a clear, credible way. Many organizations know that standardizing work improves quality and safety — yet they struggle to translate these improvements into hard numbers that decision-makers can trust.
This article explains how to calculate savings from work standardization step by step, focusing on the area where the largest and most measurable gains are created: the preparation of work instructions.
Why savings from work standardization are often underestimated
The common mistake: looking only at the shop floor. When companies estimate savings from work standardization, they usually focus on:
-
reduced errors and rework,
-
fewer incidents and safety issues,
-
faster onboarding of new employees.
While these benefits are real, they are often indirect and harder to quantify. As a result, the total savings from work standardization appear vague or “soft”.
The real constraint: instruction preparation. In practice, the biggest and most predictable cost of work standardization sits upstream:
-
creating work instructions,
-
updating and maintaining them,
-
aligning versions across departments and shifts.
This is where the largest, fastest, and most defensible savings from work standardization can be calculated.
Where savings from work standardization really come from
Time spent creating work instructions. In a traditional setup (Excel, Word, PDFs), creating one solid instruction typically requires:
-
capturing expert knowledge,
-
structuring steps and key points,
-
formatting documents,
-
reviewing and correcting versions.
Average time: ~4 hours per instruction. When organizations manage hundreds or thousands of instructions, this effort becomes a system bottleneck — consuming expert capacity that should be used for improvement, not documentation.
How digital tools unlock savings from standardization
Standardization of the standardization process. Digital platforms like etwi.io do not just digitize documents — they standardize the way standards are created.
Key changes include:
-
structured instruction logic instead of free-text documents,
-
reusable elements and templates,
-
visual, step-based formats,
-
faster review and update cycles.
Time comparison per instruction. A conservative and realistic comparison shows:
-
Traditional tools: ~4 hours per instruction
-
With etwi.io: < 1.5 hours per instruction
Savings from work standardization: 2.5 hours per instruction
How to calculate savings from standardization (step by step)
Step 1: Define the number of instructions
Count all instructions that require creation or maintenance:
-
production and assembly instructions,
-
setup and changeover standards,
-
maintenance and quality instructions,
-
onboarding and training standards.
In medium and large organizations, this number often exceeds 1,000 instructions.
Step 2: Define the hourly rate
Use a realistic, fully loaded hourly cost for the people involved:
-
process engineers,
-
production engineers,
-
CI or Lean specialists,
-
senior operators or trainers.
For clarity, we will use $40 per hour as an example.
Step 3: Apply the savings formula
Formula:
Number of instructions × 2.5 hours saved × hourly rate
Example: 1,000 instructions
Input assumptions
-
Number of instructions: 1,000
-
Hourly rate: $40 / hour
-
Time saved per instruction: 2.5 hours
Calculated savings
Total hours saved
-
1,000 × 2.5 h = 2,500 hours
FTE equivalent
-
2,500 ÷ 2,080 ≈ 1.2 FTE
Annual cost savings
-
2,500 h × $40 = $100,000 per year
These are direct, measurable savings from work standardization, based purely on reduced instruction preparation time.
Scaling savings from work standardization
Typical scenarios
1,000 instructions
-
≈ 2,500 hours saved
-
≈ 1.2 FTE
-
≈ $100,000
3,000 instructions
-
≈ 7,500 hours saved
-
≈ 3.6 FTE
-
≈ $300,000
5,000 instructions
-
≈ 12,500 hours saved
-
≈ 6 FTE
-
≈ $500,000
As the organization grows, savings from work standardization scale linearly, making them highly predictable and easy to defend in business cases.
Why these savings are only the baseline
The calculations above do not include additional benefits such as:
-
faster onboarding and shorter time-to-competence,
-
fewer errors and less rework,
-
reduced retraining caused by unclear instructions,
-
greater workforce flexibility and multi-skilling,
-
lower dependency on individual experts.
In reality, these effects often multiply the total savings from standardization.
Calculate your own savings from standardization
To make this tangible, eTWI provides a simple calculator.
How it works
Enter:
-
your number of instructions,
-
your hourly rate.
You instantly receive:
-
total hours saved,
-
FTE equivalent,
-
annual cost savings.
Example:
1,000 instructions at $40/h
= 2,500 hours saved
= ~1.2 FTE
= $100,000 per year
Final takeaway
They are about freeing critical expert capacity and redirecting it toward:
-
continuous improvement,
-
problem solving,
-
coaching and leadership,
-
scaling operational excellence.
When savings are calculated clearly and conservatively, work standardization stops being an initiative — and becomes a strategic investment.
