Rooting ideas in reality through systems engineering planning, made in Germany.

Quality management.

The term "Quality" comes from the greek philosopher aristotle and is one of 10 categories of possible linguistic expressions about a thing. It describes the "How" of a thing, which in our language is expressed by adjectives.


The traditional concept of quality in craftsmanship is based on this concept and understanding of the „HOW “of an object and therefore seeks to ensure proper and professional execution to achieve a lasting result. The skill sets to achieve them are know-how and experience. Quality management in the trades therefore controls the correct and professional execution through control processes after each work step. These are managed and documented by the master craftsman.

Industrial production.

In an industrial and project context, quality management is the creation of a quality framework for the project and the implementation of measures to ensure that the client’s standards are met with the company’s current practices. The concept of quality is not inherent to the object, but is first defined and agreed between the client and the manufacturing company.

Glasbau Hahn works with a craftsman’s and industrial understanding of quality and uses therefore three specific quality management methods for its project and product development, project and product execution and project control processes.

A difference between craft and industrial production lies in the way in which the concept of quality is defined. In an industrial context, it is not understood

in terms of the object, but is produced through an analytical process that leads to a design brief in which the client and their advisors define all functional, formal and aesthetic aspects through drawings, descriptions, standards and norms. The role of quality management is to fully understand the design brief in order to achieve a result that meets the client’s requirements and the company’s production capabilities.

In contrast to the complex planning phase of the project, Glasbau Hahn’s focus is on translating ideas into concrete, complex constructions that are made available to the client.

Project development.

The process chain begins with an understanding of the customer’s quality expectations. Glasbau Hahn uses systems engineering, the most advanced quality assurance method in project development.

Systems engineering views a museum display case as a system in which each component contributes to the success of the whole and interacts with each other.

It is essential that both Glasbau Hahn and the client understand all task in detail. This is particularly important when several consultants are involved in the project.

The first quality assurance process is therefore to check the design specifications for the display cases, considering all aspects relevant to the system.

Project execution.

Glasbau Hahn works to a quality management manual developed in conjunction with BAM, which is an integral part of the certification of the BEMMA scheme.

The Bemma scheme examines the entire production cycle and defines the individual processes and materials as well as the control systems in the manual. The manual is available in each department and is managed by the workshop foreman. Improvements are made on a regular basis, which are reviewed by our Quality Manager and incorporated into the manual as appropriate.

As the Bemma system was developed specifically for the production of low-emission museum display cases, other aspects are only partially covered. Glasbau Hahn is therefore working with responsible quality manager to continually expand the quality management manual to include all relevant aspects what make the system museum display case.

Controls based on checklists are carried out and documented after each work step and the documents are passed on in the process chain. Typical checks are based on measurements and visual and functional assessments and are documented for each individually numbered display case.

Project management.

Our project manager is the person responsible for the project.

Our project manager is involved in the system engineering process from the outset and receives all relevant information about expected quality, time and budget at an early stage. He consistently structures his schedule with milestones and measures for quality and budget control.

He communicates quality and time expectations to the production chain and carries out personal quality and efficiency checks.

If necessary, he intervenes in the process to regulate it.

He keeps the client PM informed of process developments and organises the installation side by controlling milestones such as site readiness, determining

the installation sequence with the client PM and coordinating with other contractors to achieve his goal of delivering on time, quality and budget.

Glasbau Hahn’s sophisticated quality management system is based on traditional craftsmanship and has integrated three specific quality management systems into a unique quality approach.

The owners of Glasbau Hahn have always been master-craftsmen, with the pride and dedication for their work and services, as well as 0-tolerance when it comes to quality, material and performance. The employees at Glasbau Hahn have been carefully selected and stay with the company usually for a lifetime. This guarantees a consistency of quality and extremely high skills.

The positive response of our customers to our museum display cases and the longevity of our constructions are a valid confirmation of the effectiveness of our quality management approach.
