Commerzielle und Technische Informationssysteme GmbH (CTI) is an SME in East Germany, founded in June 1990. The manager and employees came from big state-owned companies in Leipzig. CTI’s main business fields are the design, manufacture and sales of systems for time registra-tion, entry and access control or process data acquisition.

The objective of the experiment was to capture additional market shares by improving the company’s multifunctional device "CTIleancom" for time registration and access/entry control which was previously based on conventional PCB technology and OEM components. To meet this objective, microcontroller and advanced PCB technologies had to be introduced into CTI’s business. The new system allows more sophisticated registration of labour and manufacturing times. Furthermore, the entry to safety relevant areas can be checked, monitored and registered. Potential customers are all companies and public authorities.

In detail, the new solution contains a H8/3003H CPU von HITACHI. This results in faster and more complex communication capabilities, the introduction of remote control and an extended interface for peripheral equipment. Furthermore, the new solution is characterised by a lower power consumption for battery operation and a combined alphanumeric/graphic ability of the system.

Within the experiment CTI obtained knowledge in the technical management of development projects using microelectronics, the programming and application of microcontrollers, PCB design, simulation and manufacturing, as well as corresponding test strategies. Besides the technical lessons learnt CTI understood that it is best practice when introducing a new technology to co-operate very closely with an experienced and independent subcontractor. Furthermore, CTI learnt that it is necessary to spend enough time for a detailed specification in order to avoid additional design cycles later on. Additional costs for the industrialisation should be planned.

The Application Experiment was started in April 1997 and finished on time in December 1997, and the costs were 52.000 ECU as planned. These are about 40% of the total costs for the introduction of the product and its maintenance during the life cycle, which amounted to 164.4K ECU. The payback period is less than 3 years and the ROI around 130% assuming a 3 year product life cycle, and the total cost of development of 164.5K ECU.
