  7. The DesCOTS System AD Administrator Taxonomy Quality Models Users Provider or Domain Expert EVi QMj Domain Expert Evaluationsi SLk Consumer Requirements

  8. Functionalities of DesCOTS-EV • Identify the domain to which the product belongs. • Create / Select a product. • Create / Select an evaluation of a product. • Browse the quality model of the domain. • Evaluate each quality entity.

  9. DesCOTS-EV: Identify the domain -1 Expert Mode: For expert users of the taxonomy. Opening and closing the categories, until finding the desired category or domain. Software Applications Business Applications Mail Server Evaluator Multi-user Internal Software Collaboration Software

  10. Browsing the taxonomy: Expert mode Browsing the taxonomy: Expert mode Browsing the taxonomy: Expert mode DesCOTS-EV: Identify the domain - 1 Browsing the taxonomy: Expert mode

  11. DesCOTS-EV: Identifiy the domain -2 Basic Mode: For users that do not know the taxonomy. Browsing the taxonomy with the help of a wizard (taxonomy navigator) that asks questions and proposes answers that yield to the suitable domain. Collaboration Software General Purpose Collaboration Software Mail Server Evaluator Internal Communication Software Mail Server Tools

  12. Browsing the taxonomy: Basic mode Questions and proposed answers Browsing the taxonomy: Basic mode Questions and proposed answers Browsing the taxonomy: Basic mode Questions and proposed answers Mail Server Tools Domain Found DesCOTS-EV: Identify the domain - 2 Browsing the taxonomy: Basic mode

  13. DesCOTS-EV: Create / Select a product The products that belong to a domain of the taxonomy appear as special elements in the taxonomy browser. Creation of the product "TestMailServer 1.0" Mail Server Evaluator • Options that may be done on a product • Edit information registered on the product • Manage its evaluations • Delete the product and its evaluations

  14. Creating the TestMailServer 1.0 Options when we select Eudora 6.2 DesCOTS-EV: Create / Select a product Creating the TestMailServer 1.0

  15. DesCOTS-EV: Create / Select a product evaluation A product may have more than one evaluation. But it is just possible one evaluation under construction. When one evaluation is complete, the evaluation is validated in order to be used in the selection of products. Creation of an evaluation of the product "TestMailServer 1.0" Mail Server Evaluator • Options that may be done on an evaluation • Edit information registered on the evaluation • Delete the evaluation • Validate the evaluation

  16. DesCOTS-EV: Create / Select a product evaluation Creating a new evaluation for the TestMailServer 1.0 Creating a new evaluation for the TestMailServer 1.0 Options on an evaluation

  17. DesCOTS-EV: Browse the quality model As we have seen, when one evaluation is edited the quality model of the domain is presented to the user. • Browsing the quality model of the mail • server domain in order to evaluate the • "TestMailServer 1.0" • Characteristics • Subcharacteristics • Attributes (derived, basic) Mail Server Evaluator

  18. Browsing the evaluation of TestMailServer 1.0 Functionality Subcharacteristics Browsing the evaluation of TestMailServer 1.0 Folders Suitability Subcharacteristics Browsing the evaluation of TestMailServer 1.0 Suitability Subcharacteristics Browsing the evaluation of TestMailServer 1.0 Default Folders Attributes Browsing the evaluation of TestMailServer 1.0 Chacaracteristics DesCOTS-EV: Browse the quality model Browsing the evaluation of TestMailServer 1.0

  19. DesCOTS-EV: Evaluate a product The evaluation of a quality entity, depends on the metrics that these quality entities have assigned. Basic attributes - simple metrics (boolean, integer, ...) and structured (set, tuple, domain, function) Derived attributes - formula from the value of its sub-attributes Characteristics, Subcharacteristics - subjective metrics Mail Server Evaluator Assign a value to the attribute "DefaultFolders", that has a set metrics

  20. Choosing one of the possible metrics Selected values of the Default Folder attribute Possible Default Folders to choose DesCOTS-EV: Evaluate a product Assigning a value to the Default Folders attribute
