Witness (from Lanner): 
 
Simulation is used in many diverse business sectors including manufacturing, finance, electronics, retail, food & drink, automotive, defense, utilities, oil & gas, Pharmaceutical & chemical, health, transport and government.  
 Working in a simulated environment gives you the opportunity to make key decisions quickly in response to business needs as they arise. In many cases, simply by fine-tuning current business activities, with Simulation, organizations discover they are able to improve efficiency without incurring any financial investment.
 
  
 
WITNESS comprises of a suite of products addressing the issues of Interactive Business Simulation, Business and Process Mapping, Optimization, 3D visualization, Data mining & Analysis, Resource Forecasting-Planning-Scheduling. The UK-based Lanner Group (www.lanner.com) is widely acknowledged as the world’s pioneering leader in Business Simulation and Optimization.    
 
WITNESS, the world’s leading business simulation system, gives you the power and flexibility to model your working environment, simulate the implications of different business decisions and understand any process, however complex. As a result, you can always be confident that you have found the best business solution for your organization—before making a financial commitment to change.

Designed with simplicity in mind, some of the keys to its success are:
- Simple and powerful building block design
- Modular and hierarchical structure
- Easy to use standard Windows PC implementation
- Extremely interactive
- Powerful range of logic and control options
- Elements for discrete manufacture, process industries, BPR, e-commerce, call centers, health, finance and government
- Comprehensive statistical input and reports
- Quality graphical displays
- Great linkage—databases (ORACLE, SQL Server, Access, etc), direct spreadsheet links in/out, XML save formats, HTML reports, links from partner BPM and CAD applications, and more
 
 
 
The WITNESS family of simulation products includes:

Witness for Six Sigma:
 
The fundamental objective of a Six Sigma methodology is to implement a measurement-based strategy focused on process improvement and reducing internal or external variables. Most organizations when beginning a Six Sigma project ask themselves:

Because Six Sigma success is driven from metrics and process methodology, long-term success requires agile and robust technology and solutions that deliver: the metrics and measures, an integrated view of the business, simulation of “what if” scenarios and optimization of stated measures.

Lanner’s in-depth support for Six Sigma Projects includes:

These enhancements in WITNESS build on the powerful and flexible nature of WITNESS models that allows for the flexible rules that govern process operation including aspects such as resource allocation, distributional timings, complex routing and work schedules and rates. WITNESS easily handles concepts such as scrap and rework and also allows easy use and export of data to and from databases and Microsoft Excel.

Some of the new WITNESS screens offer rating statistics and a view of the results of the unique WITNESS Six Sigma Optimizer algorithm that applies intelligent search methods but limits the overall levels of change to fit in with the process.
