From Enabler to Bottleneck: When to Question Your Warehouse Setup

Executive summary

Warehouse setups are long-term investments that have a decisive impact on service performance, cost efficiency and operational stability.

As business models, order structures and service requirements continue to evolve, many existing warehouse setups increasingly struggle to keep pace, often without this becoming immediately visible in day-to-day operations.

The UK continues to battle rising labour costs, ongoing labour availability issues and increasing service expectations, which further amplify the impact of misaligned warehouse technology on operational performance.

Why the warehouse setup matters today

The warehouse setup matters because it directly influences the resiliency, scalability and competitiveness of operations

With recent disruptions in global supply chains, warehousing has gone from an afterthought to a key part of an effective business. Below are some examples of why businesses have changed focus

The warehouse as a strategic enabler

The UK public now expects next-day, or even same-day delivery, with no room for error and for the right price. Warehouse performance plays a particularly critical role in maintaining competitiveness for consumers ready to switch providers at any time.

Warehouse performance is no longer just an operational issue - it is a business-critical factor.

Warehouse setups often reflect past business realitiesr

Most warehouse setups were designed to meet the requirements of a specific business model at a given point in time. In many UK operations, these setups are now required to support more complex order structures, shorter lead times and dynamic product ranges than originally anticipated.

Many UK warehouses are still designed for conditions that no longer fully apply.

Limited space increases the importance of using existing assets effectively

Growing volumes, higher throughput requirements and increasing complexity place additional demands on warehouse operations. In the UK, prohibitive costs, limited land availability and planning constraints mean that capacity cannot be created through new warehouses, but must be generated within existing buildings through better use of space, processes and technology.

When expansion is not an option, the effectiveness of the existing warehouse setup becomes critical.

The need to question the setup often emerges gradually

Warehouse setups rarely become ineffective overnight. Instead, increasing workarounds, gradually rising labour dependency and a lack of data slowly indicate a growing mismatch between setup and business needs, long before problems make it to board-level.

Persistent operational friction is a strong indicator that the warehouse setup should be reviewed.

Triggers indicating that your warehouse technology is reaching its limits

How many of these indicators apply to your warehouse setup?

Take note of how many triggers apply to your warehouse. If you are seeing a lot of boxes ticked then it is likely time to review your facility for potential improvements.

Business-related triggers

Sustained volume growth that exceeds original design assumptions
Significant increase in SKU count or product range complexity
Introduction of new sales channels (e.g. e-commerce)
Higher service level requirements or shorter delivery lead times

Operational warning signs

Overtime, temporary staff or shift extensions are required on a regular basis
Temporary workarounds have become part of daily operations
Bottlenecks repeatedly occur at the same processes
Picking errors, rework or exception handling are increasing
Training new staff takes longer and productivity ramps up slowly
Absence of key employees immediately impacts performance
Processes are increasingly dependent on individual experience rather than standardisation
Layout constraints lead to long travel distances or congestion
Operational planning becomes increasingly complex and reactive
Peak periods cause disproportionate stress on operations

Technology and system-related indicators

Limited scalability without disproportionate cost increases
Low flexibility to adapt layouts, processes or material flows
Existing automation no longer fits the SKU range or order profile
Growing number of manual workarounds to support automation
System changes require high effort or long lead times
Interfaces between systems require frequent manual intervention
Limited system transparency or data availability for decision-making

Why waiting is often the most expensive option

Delaying action typically leads to steadily rising operating costs through additional labour and workarounds.
Structural weaknesses increase operational risk and reduce stability, especially during peak periods.
Postponing decisions limits flexibility and forces reactive choices under time pressure.
Early, structured assessment preserves options and enables informed, sustainable decisions.

How can you take steps to improve?

Employ continuous improvement

Recruit in employees trained in continuous improvement or Lean processes to help identify and plan for opportunities to improve

Engage external experts

Engage external experts to conduct a warehouse assessment. This can help to benchmark your operation and create a structured and business-case backed implementation plan

Conduct regular operations audits

Create internal audits that the operations team can periodically investigate to catch issues early. This will help to identify an action plan before challenges turn into catastrophes.

Now is the right time to review the fitness of your warehouse setup.

Warehouse setups rarely fail suddenly - they become constraints when they are no longer questioned.
