 Product line approach: development of a generic platform from which numerous different products can be derived.  Example: Nokia’s cell phone line

 Develop web-based feature manager tool  Main elements:  Feature Tree Management  Product Management  Feature Tree Editing  Product Definition

 Development Methodology:  Weekly iterations – review current status, choose stories for next iteration  Incremental evolution – code is always runnable  Main tools:  Java over Eclipse  Spring MVC framework  Dojo/Dijit libraries  JSON format  Derby database

 The feature manager tool consists of  Client-side code  Server-side code  Database

 Receives requests from the client and responds accordingly.  Data requests for client  Update requests  Saves system data in a persistent database  Checks input received from client for errors  Reports errors on server side to client  Includes automatic testing 6

Feature Tree Management  Supports creation of a new feature tree  Supports edit/remove/rename an existing feature tree  Displays information about selected feature tree 7 Dojo Filtering Select: based on JSON data store

Product Management  Create a new product based on an existing feature tree  Edit/Remove/Rename a product  Displays information about selected feature tree 8 Dojo Filtering Select: based on JSON data store

Feature Tree Editor  Receives id of the wanted feature tree in url  Displays current feature tree  Displays information about selected item in feature tree  Allows renaming of tree  Allows add/remove/rename of feature  Allows creation of dependencies between features using exclusion/inclusion lists

Feature Tree Editor

Product Definition  Receives product id in URL  Displays feature tree with selection buttons  Displays information about selected product and features  Constraints between features are supported, error message appears if bad selection is made

Product Definition

 Web applications are complex  Many frameworks and libraries  Frequent meetings are vital to the progress of the project.  On a large scale project, appropriate work methods and infrastructures are crucial for the ongoing success of the project.  Repository  Code reviews  Project was a great platform for learning new technologies and how a project is executed in the “real world” 13
