In another article, I introduce the model we will use to illustrate the complexity of this exercise with two scenarios:
- Scenario 1: your finance director wants to minimize the overall costs
- Scenario 2: sustainability teams push to minimize CO2 emissions
Model outputs will include financial and operational indicators to illustrate scenarios’ impact on KPIs followed by each department.
- Manufacturing: CO2 emissions, resource usage and cost per unit
- Logistics: freight costs and emissions
- Retail / Merchandising: Cost of Goods Sold (COGS)
As we will see in the different scenarios, each scenario can be favourable for some departments and detrimental for others.
Do you imagine a logistic director, pressured to deliver on time at a minimal cost, accepting the disruption of her distribution chain for a random sustainable initiative?
Data (may) help us to find a consensus.
Scenario 1: Minimize Costs of Goods Sold
I propose to fix the baseline with a scenario that minimizes the Cost of Goods Sold (COGS).
The model found the optimal set of plants to minimize this metric by opening four factories.
- Two factories in India (low and high) will supply 100% of the local demand and use the remaining capacity for German, USA and Japanese markets.
- A single high-capacity plant in Japan dedicated to meeting (partially) the local demand.
- A high-capacity factory in Brazil for its market and export to the USA.
- Local Production: 10,850 Units/Month
- Export Production: 30,900 Units/Month
With this export-oriented footprint, we have a total cost of 5.68 M€/month, including production and transportation.
The good news is that the model allocation is optimal; all factories are used at maximum capacity.
What about the Costs of Goods Sold (COGS)?
Except for the Brazilian market, the costs of goods sold are roughly in line with the local purchasing power.
A step further would be to increase India’s production capacity or reduce Brazil’s factory costs.
From a cost point of view, it seems perfect. But is it a good deal for the sustainability team?
The sustainability department is raising the alert as CO2 emissions are exploding.
We have 5,882 (Tons CO2eq) of emissions for 48,950 Units produced.
Most of these emissions are due to the transportation from factories to the US market.
The top management is pushing to propose a network transformation to reduce emissions by 30%.
What would be the impact on production, logistics and retail operations?
Scenario 2: Localization of Production
We switch the model’s objective function to minimize CO2 emissions.
As transportation is the major driver of CO2 emissions, the model proposes to open seven factories to maximize local fulfilment.
- Two low-capacity factories in India and Brazil fulfil their respective local markets only.
- A single high-capacity factory in Germany is used for the local market and exports to the USA.
- We have two pairs of low and high-capacity plants in Japan and the USA dedicated to local markets.
From the manufacturing department’s point of view, this setup is far from optimal.
We have four low-capacity plants in India and Brazil that are used way below their capacity.
Therefore, fixed costs have more than doubled, resulting in a total budget of 8.7 M€/month (versus 5.68 M€/month for Scenario 1).
Have we reached our target of Emissions Reductions?
Emissions have dropped from 5,882 (Tons CO2eq) to 2,136 (Tons CO2eq), reaching the target fixed by the sustainability team.
However, your CFO and the merchandising team are worried about the increased cost of sold goods.
Because output volumes do not absorb the fixed costs of their factories, Brazil and India now have the highest COGS, going up to 290.47 €/unit.
However, they remain the markets with the lowest purchasing power.
Merchandising Team: “As we cannot increase prices there, we will not be profitable in Brazil and India.”
We are not yet done. We did not consider the other environmental indicators.
The sustainability team would like also to reduce water usage.
Scenario 3: Minimize Water Usage
With the previous setup, we reached an average consumption of 2,683 kL of Water per unit produced.
To meet the regulation in 2030, there is a push to reduce it below 2650 kL/Unit.
This can be done by shifting production to the USA, Germany and Japan while closing factories in Brazil and India.
Let us see what the model proposed.
It looks like the mirrored version of Scenario 1, with a majority of 35,950 units exported and only 13,000 units locally produced.
But now, production is pushed by five factories in “expensive” countries
- Two factories in the USA deliver locally and in Japan.
- We have two more plants in Germany only to supply the USA market.
- A single high-capacity plant in Japan will be opened to meet the remaining local demand and deliver to small markets (India, Brazil, and Germany).
Finance Department: “It’s the least financially optimal setup you proposed.”
From a cost perspective, this is the worst-case scenario, as production and transportation costs are exploding.
This results in a budget of 8.89 M€/month (versus 5.68 M€/month for Scenario 1).
Merchandising Team: “Units sold in Brazil and India have now more reasonable COGS.”
From a retail point of view, things are better than in Scenario 2 as the Brazil and India markets now have COGS in line with the local purchasing power.
However, the logistics team is challenged as we have the majority of volumes for export markets.
Sustainability Team: “What about water usage and CO2 emissions?”
Water usage is now 2,632 kL/Unit, below our target of 2,650 kL.
However, CO2 emissions exploded.
We came back to the Scenario 1 situation with 4,742 (Tons CO2eq) of emissions (versus 2,136 (Tons CO2eq) for Scenario 2).
We can assume that this scenario is satisfying for no parties.
The difficulty of finding a consensus
As we observed in this simple example, we (as data analytics experts) cannot provide the perfect solution that meets every party’s needs.
Each scenario improves a specific metric to the detriment of other indicators.
CEO: “Sustainability is not a choice, it’s our priority to become more sustainable.”
However, these data-driven insights will feed advanced discussions to find a final consensus and move to the implementation.
In this spirit, I developed this tool to address the complexity of company management and conflicting interests between stakeholders.
