QuesoMex
About the company
• Belongs to one of the biggest private groups in Mexico• Sells cheese in Mexico, United States, centre- and south
America• One of the three leading companies in the cheese sector
in Mexico.• Production: Gouda, Oaxaca, Cream, Manchego,
Mozarella… representing 80 000 tons/year (2006)• It bought two competitors during the last 3 years, closed
2 plants and moved production to the other plants.• Today, 5 plants are working (in Mexico) and selling 30
different brands.
1. Accounting System
• Traditional accounting system• The group is slowly implementing SAP in its subsidiaries
except the “cheese” one:– Too many different products processed and bundled differently: too
many different activities.– Not enough employees able to manage an ABC system.
• One department “cost control” is responsible for accounting: – Their job is to receive, adapt and deliver figures from the 11 cost
centers of the factories: production, milk logistics (very important!), warehouse, overhead, etc.
– They do not to analyze the figures– They don’t understand them! (just numbers…)
2. Glossary of the costs
• Variable costs:– Raw material: liquid or dry milk, proteins, sugar/salt,…– Packaging: plastic bags, cardboard, boxes used for
transportation
• Fixed costs:– Wages and related costs;– Energy (considered as a fixed cost, even if it should be a
degressive variable cost)– Maintenance (spare parts, repairs, some functions being
outsourced);– Amortization and depreciation of machines and equipment
2. Glossary of the costs
Costs benchmarking in 2 factories:
• Plant in Celaya, in the north, near the border of USA:– Very manual,– Many issues with workers (permanently leaving the company for
crossing the border in order to work in the USA)– Many issues of quality (losses for quarantine/waste)– 300 different SKUs, with 10 different types of cheese.Plant in
• Lagos, in the center of the country: – quite automatized;– ISO 14001– In the same complex than the Yogurt factory of the group (in
order to merge logistics and administration)– 200 different “SKUs” (Stock Keeping Unit: each of the distinct
products sold by the company), but only 15 different cheeses.
Costs benchmarking in 2 factories:
Costs Benchmarking
• 86%(C) / 93%(L) of the costs come from raw material & packaging!
• “Other costs” are costs from the group (including marketing, logistics…)

• As we can see, the plant in Lagos is much more automatized: amortization is much more important and wages are slightly lower (less employees (150 against 300).
• Machines in Celaya are old and need a lot of maintenance.

3. Analysis of activities for one representative production line
Line of “Panela” cheese• Official initial efficiency: 97,8% ( considering the
percentage of produced vs forecasted!)• A nominal speed was redefined with the line
manager.• Observation made during one representative
day.
Result: 44% of efficient work/ “value-added” during the day
• Methodology: machine working without product/not following the nominal speed.
• Change-overs: changing presentation of cheese.• “lunch” pause: time lost after lunch for coming
back to machines

4. What would we do? (1)• As the cost of raw material is extremely high, losses are primordial
(they represent 8% of raw material). In order to minimize them, we would reorganize and simplify the work:– Reduce number of products: for the moment, there is packaging of
100g, 200, 400, 450, 500, 600, 700, etc. until 1,1kg and same cheese that are sold with the same weight but with many different brand names. We would reorganize the packaging of the product: fewer sizes, fewer brands.
→ Partly done (-40% of SKUs) reducing the time “lost” for change-overs.– Organize the work: Currently, processes and actions are not organized
(no nominal speed defined, tasks not defined): we would define an organization and set up a real rhythm by using efficiency data and a record of losses.
→ Done for most products.– Set up a system of continuous improvement: using data of efficiency
and losses defined for every shift, we would help line managers to find the origins of time wasted and of the losses in order to minimize them day after day.
→ efficiency raised by 30%→ Losses reduced (from 8 to 4%)
Current situation, example for the Panela line
• Cost of raw material decreased: 8% of raw material was reusable by minimizing waste and controlling better the amount of water in the cheese, but the raw material raised by 4% (current global trend)
• Costs of energy are increasing even if the consumption decreased by 11% (increasing price of oil and electricity)
• Roughly 15% of employees left the company and were not replaced
• Same figures for the other product and for the project in general: calculated current savings of 5,9M$ (without considering increasing prices of raw material and energy)

What would we do? (2)• As we simplified the number of SKUs, it would be much easier to implement
an ABC system.→ To be done
• Consequently, it would be possible to define prices for every SKU that are much more relevant.
• With this database of costs, plant managers can much more easily decide to:
– launch a new product; – Decide to keep or not all the products.
• The factory, being more efficient, temporarily doesn’t need to find workers for replacing those who leave for the USA (-40% of employees). Wages can be raised in order to keep more easily the employees.
→ To be done… • Reducing the number of SKUs and brands allows marketing to make
economy of scale, their work is simplified.→ To be done
