Industry: Manufacturing Learn more about Tableau and big data in our whitepaper. When the system behavior is different for different input and not same for a range of inputs, both equivalent partitioning, and boundary value analysis won't help, but decision table can be used. For n = 10, which is very common in the web based testing, having big input forms, the number of combinations will be 1024. The process of collecting relevant data and submitting reports to management took at least two days, which meant that the company could only make decisions and roll out strategy changes on a weekly basis. Manufacturing companies can use equipment details like manufacturer and condition, number of product runs and types of loads, and maintenance records to create a maintenance scoring system or the likelihood of equipment needing maintenance.
