The model development process is using advanced algorithms for searching the right training set that generates the best model. The time it takes to build the model can take few minutes, or few hours, depending on the system's configuration.
A graphic tool for model building is available for users who are interested in controlling the behavior of the final model. For example, when first installing the product, some users want to get up and running quickly with few lab measurements. After a week or two, more lab data is available and the model becomes more mature and covers a larger range of lab values.
Normally, the manual tool is used at the beginning of the integration process, and it is not needed afterwards.
