Lanner provides businesses with superior technologies that enable value discovery, improve process understanding, support process change and result in superior decisions, both strategic and operational.
Lanner's rich heritage goes back as far as 1978, when the world's first visual interactive simulation tool was developed in the operational research department of British Leyland Motors, which subsequently became AT&T Istel. Lanner Group was formed by an MBO from AT&T in 1996 and is now recognised as the world's leading business process simulation and optimisation organisation. This wealth of knowledge has been retained through many loyal and talented members of today's team. This team is dedicated to providing business managers and service owners with a better and quicker way of optimising delivery and process performance today, providing technologies and expertise to release long term value for our customers. See Lanner's history - "in it for the long term".
With offices in Europe and the United States and team members representing more than 500 years of relevant experience, Lanner works with leading companies and government organisations around the world. A global network of experts and partners helps us to provide a similarly agile response worldwide. Lanner's leading WITNESS simulation modelling technology enjoys a rich pedigree, having now helped over 5000 organisations worldwide that span the manufacturing, service and government sectors. Our reputation is strong because we enable business and process value discovery and deliver process performance improvements that drive sustainable bottom line results. Our customers tell us that the combination of our pioneering technologies and expertise cannot be matched.
Lanner's advanced simulation technology is supplied to simulation professionals and operational users through its WITNESS® brand. Lanner's L-SIM® brand has quickly established itself as the leading embedded simulation engine used in enterprise suites for the top software solution suppliers. Lanner has developed a new architecture and methodology for rapid development of niche decision support applications using its simulation technology at the core. Software applications such as PRISM - the virtual police force and Px-SIM - for pharmaceutical process efficiency are the result of significant investment by Lanner, with further focused sector applications planned for the future.
The time line below shows the origins of Lanner's software in 1978 in British Leyland to its leading position today and the foundation of its exciting new developments of today.
