Margin up 5.6 points, broken down

Scroll and the chart above breaks one figure from my engagements into its causes, the ones that added and the ones that took away. Every report I write ends like this: one large number you can check all the way down to its data.

Three engagements, written with their numbers

Snack factory, East Java

Sales rose three years running while net profit fell. The owner assumed ingredient costs; in fact eighty two products were sold at prices never recalculated since 2019.

Gross margin rose from 18.4 to 24.0 percent in eleven months: repricing +4.2, materials -1.6, shrinkage +2.1, labour -0.9, delivery +1.8. Fourteen products were discontinued, and nobody was laid off.

Pricing and cost202511 months

Building materials distributor, Sumatra

Eight warehouses holding twenty one billion rupiah of stock, each recording it differently.

Stock fell 31 percent with no loss of sales, and 6.4 billion rupiah of cash came back within seven months.

Inventory20247 months

Private hospital, West Java

Outpatient waiting averaged 94 minutes with complaints rising monthly. Management was sure they needed more doctors.

Waiting fell to 38 minutes with no new doctors, by changing scheduling and registration order. Two clinics moved floors.

How I work

Two days a week on siteWorking with the existing teamHandover to an internal successorReports with their raw data

What I do not do

Recommendations without executionProjects staffed by juniorsMass redundancies

The same way of working every time

  1. Two weeks reading

    I read two years of data and walk the site without changing anything. It ends in one page with three hypotheses and the numbers that support or weaken each.

  2. One small change first

    The first change is always the easiest to undo, so the team sees this is not an upheaval. Usually in week three.

  3. Two days a week on site

    Not meetings, but standing where the work happens. Changes are agreed with the people who do them, not announced to them.

  4. An internal successor from the start

    Someone from the team is named as successor in month one, not in the last month. They run the numbers meeting from month four.

  5. Handover and report

    The final report carries raw data, the calculation files, and a list of what is unfinished. I answer questions free for three months after.

Try to reverse the order and the machine will not have it
