Creation of a specification sheet for the introduction of an ERP system

WISTRO Elektro-Mechanik GmbH is a medium-sized specialist for the development, production and sales of industrial fans. The main products include forced ventilation units for drive technology, which are used in all areas of industry and commerce. In addition to the original production of fan units, an efficient sheet metal production facility has been built up in recent years, which can be used to meet individual customer requirements in an application-oriented manner. The ERP system, which has been in use for many years, has shown considerable weaknesses in process support and order processing over time. Moreover, support and future viability were not guaranteed due to the dependence on a relatively small supplier. In order to speed up procedures and processes, to improve the flow of information and to realize a future-proof system landscape, a preparatory specification for the introduction of an ERP system was to be drawn up.

“With the help of GREAN we have comprehensively recorded our current processes. Improvement potentials were systematically identified and transferred into a structured ERP specification sheet, which fully represents our needs and wishes. Finally, GREAN helped us with the final selection of providers and systems. This way we can say that we are sure to have chosen the right one for us from a variety of possible ERP systems.”

Sönke Strohmeyer (Managing director WISTRO Elektro-Mechanik GmbH)

In a first project phase, the current ERP-relevant business processes as well as the IT infrastructure were jointly recorded in workshops and weaknesses in system support, fields of action and optimization potential were identified. Based on the ACTUAL analysis, GREAN and WISTRO developed a TARGET process model through structured workshops. Together with the key users, the functional requirements of the future ERP system were determined and transferred into a specification sheet. In order to decide on the future ERP system and provider, GREAN first carried out a pre-selection of suitable providers on the basis of a “matching” process (checking the fulfilment of requirements by providers / systems). Finally, the final decision was made on the basis of structured supplier workshops and a comparative evaluation of the suppliers’ offers.

In detail, the following services were provided:

  • Recording and presentation of the ACTUAL process landscape

  • Identification and documentation of weak points, fields of action and optimisation potential

  • Development of a TARGET process model

  • Derivation of basic requirements for the ERP system

  • Transfer of the requirements into a specification sheet

  • Preselection of suitable ERP system providers

  • Angebotseinholung und -vergleich

  • Implementation of supplier workshops

  • Decision support in the final selection of an ERP system and provider


Factory planning

New construction on a greenfield site or expansion of existing buildings - we offer you comprehensive advice and sophisticated planning services for a well conceived factory. For us, this includes basic master and factory structure planning as well as support for your project right through to implementation. Whether new or reorganisation planning - we are experts in factory planning.

Process optimization

In many factories, high inventories, long travel, search or lead times are a major cost factor, which at the same time massively reduces production efficiency. This is what we do: Our customers benefit from well-founded, systematic and analytical consulting. In this way, we work with you to increase the efficiency of your production.

Resource efficiency

High and ever increasing material and energy costs are becoming an efficiency problem in many factories. We systematically investigate where potential is lying dormant and then identify meaningful and economical measures for improvement. In this way we increase the material and energy efficiency in your factory - and at the same time reduce your energy bill.
