What it means
The method starts by listing what the organisation actually does, then classifying each activity as value-added or non-value-added. Value-added activities change the product or service in a way the customer cares about, while non-value-added activities such as rework, waiting, moving material and duplicate approvals consume cost without adding anything the buyer values.
This matters because most cost-cutting programmes attack budgets rather than causes. Cutting a department's spending by 10% removes capacity but leaves the underlying work in place, whereas removing the reason an activity exists takes the cost out permanently.
Activity-based management is usually described in two layers. Operational activity-based management is about doing things right, meaning making existing activities faster and cheaper, while strategic activity-based management is about doing the right things, meaning changing the mix of products, customers and channels the business serves.
The practical work is unglamorous: map the process, attach costs to each step, measure the proportion of cost that is non-value-added, then attack the largest items with process redesign, automation or supplier changes. Progress is tracked with a value-added ratio, which is value-added cost divided by total activity cost.
The common failure is treating it as a redundancy exercise. If the only visible outcome of the analysis is job losses, staff stop supplying honest process information and the second round of improvement never happens.
In practice
Real-world examples.
Example
A furniture maker maps its finishing process and finds that moving part-built frames between two buildings costs $95,000 a year and adds nothing a customer would pay for. Relocating the finishing line removes the activity rather than trimming its budget.
Example
An insurer analyses claims handling and discovers that a second internal approval on low-value claims costs more than the claims it occasionally corrects. Raising the approval threshold removes the step and speeds up settlement.
Example
A distributor uses cost-to-serve analysis to show that its smallest customer segment costs more to service than it generates in gross margin. Rather than dropping those accounts, it moves them onto a self-service portal with a minimum order value.
Formula
Calculation
Value-Added Ratio = Value-Added Activity Cost / Total Activity Cost
A manufacturer maps its processes and finds total activity cost of $2,400,000 a year. The analysis classifies 25% of that as non-value-added: $2,400,000 x 25% = $600,000, made up of rework, internal material movement, expediting and duplicate quality checks.
Starting value-added ratio = ($2,400,000 - $600,000) / $2,400,000 = $1,800,000 / $2,400,000 = 75%.
The improvement team judges that 40% of the non-value-added cost can be removed within a year through cell layout changes and a single approval step: $600,000 x 40% = $240,000 of annual saving.
New total activity cost = $2,400,000 - $240,000 = $2,160,000, with non-value-added cost falling to $600,000 - $240,000 = $360,000.
New value-added ratio = $1,800,000 / $2,160,000 = 83.3%. The business now spends the same $1,800,000 on work customers value, and $240,000 less on work they do not.Case study
Seen in the real world.
Ferndale Components is a fictional engineering firm presented here as an illustrative example. Facing margin pressure, its board initially proposed a flat 8% cut to every departmental budget.
The operations director asked for six weeks to try a different approach. Mapping the plant's activities produced total activity cost of $2,400,000, of which $600,000, or 25%, was classified as non-value-added: rework on two problem parts, material shuttling between buildings, expediting late orders and a duplicate inspection step. The value-added ratio stood at 75%.
The team targeted the largest items and removed $240,000 of that non-value-added cost within the year by relocating a machining cell, fixing the two parts causing most rework, and deleting the duplicate inspection. Total activity cost fell to $2,160,000 and the value-added ratio rose to 83.3%, delivering a bigger saving than the proposed across-the-board cut while leaving capacity for value-adding work untouched.
Watch out
Common mistakes.
- Treating activity-based management as a cost-cutting exercise aimed at headcount, which destroys the trust needed to get accurate process information.
- Labelling activities non-value-added without asking why they exist, then removing a control or check that was preventing a much larger problem.
- Investing in a detailed activity analysis and then never changing anything, so the exercise produces a report rather than a saving.
Questions
People also ask.
How is this different from activity-based costing?
Activity-based costing calculates what activities cost, while activity-based management uses those figures to decide what to change, improve or stop.
Are all non-value-added activities removable?
No, some are required by law, safety rules or contracts, and these are usually classed as business-value-added and managed for efficiency rather than eliminated.
Where do most businesses start?
Usually with one high-cost process such as order fulfilment or claims handling, since a single visible win builds the case for wider analysis.
