Usage-based Models Improve Odds in Software Testing

The need to test products of all kinds, software and physical products, often runs into challenges connected with: What to test? How to test? How long, how many tests to run? How to document the risk remaining after test? Software is particularly challenging because the properties worth exercising and assessing in tests are hard to…

Capabilities of Neural Network as Software Model-Builder

One branch of computational intelligence tools, neural networks, is worth surveying as part of the extended data mining and modeling toolkit. The focus here is on a specific kind of neural network applied to empirical model-building – comparing and contrasting its capabilities and performance to more traditional tools like regression analysis. Neural Networks Mimic Biological…

Creating a Fresh View of Six Sigma Data and Tools

Six Sigma DMAIC and DFSS roadmaps provide the guidance needed for using facts and data to understand problems, opportunities and solutions to get results in a wide variety of project settings. For the routine cases, they give practitioners what they need. There are some situations, though, that can benefit from a broader view of Six…

Faster Deployment for Europe’s Small and Medium Businesses

To initiate a continuous improvement program, small- and medium-sized businesses must refine the deployment model to meet their needs. This is particularly important in Europe, with the typical European company being smaller than its U.S. equivalent. By Thomas Bertels Large multinational firms such as General Electric, Honeywell and Motorola proved the value of Six Sigma…

Opening the Door for Process Standardization in Europe

By understanding the differences and the commonalities between local processes, European businesses can start to assemble a pan-European process to satisfy the needs of each country, opening the door for process standardization and resource pooling. Processes which deliver value to customers across a wide geographic area in the United States are considerably less complex than…

Debunking IT Isolation in Search of Quality and Savings

Often considered an island unto itself, technology development and implementation does not really occur in a vacuum. However, the interrelated nature of managerial, quality and technological systems, and the inherent benefits of a truly integrated view are not necessarily evident to the information technology (IT) professional. Consequently, increasing implementation costs and an array of idiosyncratic…
