Disruption is no longer the exception. Is your supply chain planning keeping up?

During our recent webinar on El Niño, an interesting question emerged: is the potential impact significant enough to warrant a separate plan, or should it be considered as part of normal supply chain planning?

It raises a much broader issue.

Supply chains face disruption from multiple directions: climate events, geopolitical developments, trade restrictions, transport constraints and changing customer demand.

These challenges aren't necessarily new. What's difficult is that they can overlap, develop unpredictably and affect different parts of a business in different ways.

If disruption is part of the normal operating environment, shouldn't our planning reflect that?

Planning for uncertainty, not just the expected outcome

Many planning processes are built around an expected outcome: anticipated demand, available supply, agreed lead times and planned inventory levels.

But what happens when those assumptions change?

Businesses cannot realistically develop a detailed contingency plan for every possible disruption. Nor would it make commercial sense to protect against every risk.

Instead, planning needs to accommodate uncertainty from the outset.

That means understanding which assumptions matter most, exploring what happens when they change and identifying the decisions the business might need to make.

From identifying risks to making decisions

Recognising a potential disruption is relatively straightforward. Deciding what to do about it is considerably harder.

Take El Niño. A business might anticipate potential pressure on raw material availability or transport costs. But does that justify buying earlier, holding additional stock or exploring alternative suppliers?

Each option has implications for service, cost and working capital. Acting too early can be expensive. Waiting too long can be equally costly.

This is where scenario planning becomes valuable. Not as an exercise in predicting exactly what will happen, but as a way of understanding different outcomes and the consequences of possible responses.

What does this mean in practice?

Four questions are worth asking:

1. How dependent are our plans on assumptions that could change? Identify the factors that would have the greatest impact on supply, demand, service or cost.

2. Do we understand our options?
Consider what could realistically be changed, how quickly and at what cost.

3. Do we know what would trigger action?
Agree which developments would justify intervention, rather than reacting to every new warning.

4. Can our planning processes respond quickly enough?
Ensure that changing circumstances can be assessed and decisions made without starting a separate planning exercise every time.

The fundamentals still matter

Disruption may be increasingly familiar, but the fundamentals of good supply chain management haven't changed.

Businesses still need to balance service, cost, inventory and cash. They still need reliable information, clear responsibilities and effective decision-making.

The difference is that planning can no longer assume things will unfold as expected.

The objective isn't to predict every disruption or eliminate every risk. It's to build the capability to make informed decisions when circumstances change.
