Coming back to SharePoint world after one month without thinking on it. Some necessary research about resources that potentially can enable us to advance in the construction of real solutions for our client.

The most interesting for me are:
Manufacturing Process Management
The Manufacturing Process Management application template helps teams to model and track manufacturing processes as well as tasks and issues that arise in the upkeep of these processes.
Case Management for Government Agencies
The Case Management for Government Agencies application template helps case managers track the status and tasks required to complete their work. When a case is created, standard tasks and documents are created which are modified based on the work each case manager has completed.
Employee Activities Site
The Employee Activities Site application template helps manage the creation and attendance of events for employees. Activity owners use the site to review proposals for new activities and create event calendar items. Employees use the site to sign up as well as track which activities they’ve attended in the past.
Employee Training Scheduling And Materials
The Employee Training Scheduling and Materials application template helps instructors and employees manage courses and related materials. Instructors can use the site to add new courses and organize course materials. Employees use the site to schedule attendance at a course, track courses they’ve attended and to provide feedback.
