Technical specifications should describe what the production system actually needs to achieve — not simply what can be purchased.

In complex manufacturing, a technically correct purchasing specification is essential for achieving the expected result.

A supplier can deliver exactly what has been specified. Yet the equipment, material or complete system may still fail to meet the actual production requirements if the original specification was not sufficiently connected to real operating conditions.

From Technical Purchasing Specification to Real Production

Purchasing specifications are often developed from existing standards, previous purchases, supplier information or internal requirements.

These sources can be useful, but they do not always describe the complete technical requirements of the actual production process.

A functional Technical Specification should consider the relationship between:

Material → Process → Equipment → Production → Quality → Maintenance → Recycling → Final Application

The objective is to ensure that the requirements communicated to suppliers reflect the conditions in which the equipment, material or system will actually operate.

The Technical Specification Is Part of the Solution

The purchasing process itself is rarely the technical problem.

Purchasing teams are expected to purchase according to the requirements defined by the organisation.

The critical question is therefore:

Are the requirements in the specification technically and practically sufficient to achieve the intended production result?

If important requirements are missing, unclear or based on assumptions rather than actual operating conditions, the supplier may still deliver exactly what was ordered.

The result can nevertheless be:

• Lower production capacity
• Unstable production
• Excessive material consumption
• Increased waste
• Quality problems
• Unexpected maintenance requirements
• Higher energy consumption
• Unplanned downtime
• Expensive modifications after installation

Technical Specifications Must Reflect Reality

A specification should not only describe what the organisation wants to buy.

It should describe what the system must accomplish.

This requires an understanding of the actual application, including:

• Material characteristics
• Material variation
• Processing conditions
• Production speed
• Temperature and pressure
• Equipment limitations
• Product requirements
• Quality requirements
• Maintenance requirements
• Safety requirements
• Environmental conditions
• Recycling and waste requirements

The more complex the process, the more important this system-level understanding becomes.

Polymer System Optimization

Polymer System Optimization provides a framework for connecting materials, processes, equipment and production requirements.

Instead of looking at the purchasing specification as an isolated document, we consider how the specified requirements affect the complete production system.

Material → Formulation → Process → Equipment → Production → Recycling & Reuse → Final Application

This approach can help identify technical gaps before they become purchasing, commissioning or production problems.

When the Supplier Delivers What Was Specified

A common situation in industrial projects is:

The customer specifies the equipment.
The purchasing organisation purchases the equipment.
The supplier delivers the equipment.
The equipment meets the specification.
The production result is still not achieved.

This does not necessarily mean that the supplier failed to deliver.

It may indicate that the original specification did not fully describe the technical requirements needed for the intended application.

Understanding this distinction can be critical when analysing production problems.

What We Can Help Evaluate

PU Consulting AB can help manufacturers review the connection between technical requirements and real production conditions.

Depending on the project, this may include:

• Technical specification review
• Material requirements
• Process requirements
• Equipment requirements
• Production capacity requirements
• Quality requirements
• Energy and material efficiency
• Waste and recycling requirements
• Maintenance considerations
• Supplier technical documentation
• Equipment selection
• Process and equipment compatibility

The objective is not to make specifications unnecessarily complicated.

The objective is to make them technically meaningful and connected to the actual application.

Before the Purchase

A technically strong purchasing specification can help answer important questions before an order is placed:

What must the system achieve?

Under which operating conditions?

With which materials?

At what production rate?

With what quality requirements?

What happens when material properties vary?

How will maintenance and downtime be managed?

What happens to production waste?

How will the equipment interact with the rest of the production system?

These questions can be more important than simply specifying a machine model, capacity or supplier.

From Specification to Measurable Performance

The ultimate objective is not a specification document.

The objective is production performance.

A well-developed specification should provide a practical connection between the organisation’s requirements, the supplier’s solution and the conditions under which the system will operate.

That connection can help reduce the risk of expensive modifications, unstable production and unexpected performance gaps after installation.

PU Consulting AB

PU Consulting AB works across materials, processes, equipment and industrial applications.

With more than 35 years of practical experience, we help manufacturers identify technical relationships that may otherwise remain separated between purchasing, engineering, production, maintenance and suppliers.

Our approach is based on understanding the complete system rather than optimising one component in isolation.

The goal is simple:

Specify what production actually needs — then connect the right materials, processes, equipment and expertise to achieve it.

Start with a Technical Specification Review

If you are preparing a new purchasing specification, reviewing an existing specification or experiencing a gap between specified and actual production performance, PU Consulting AB can help evaluate the technical requirements.

Start with the specification.
Understand the production requirement.
Then select the solution.
