1.1. Problem Statement

The general problems to be addressed by the Calendar Tool project are the following:

  1. to provide a reliable and easy to use software tool that manages an individual user's calendar

  2. to provide a secure group environment that manages a collection of individual calendars for the purposes of group scheduling and information sharing
While these problems have been solved by a number of commercially available and public domain products, the Calendar Tool provides a solution with certain functional improvements over existing tools. Specific problem areas are the following:

  1. scheduling multi-user meetings

  2. dealing effectively with overlapping events

  3. providing a wide range of calendar viewing options

The Calendar Tool project addresses the requirements a particular customer. This customer needs a Calendaring tool with a collection of features not available in any single existing tool. This aspect of the problem is one of combining a set of existing features in a way that these features have yet to be combined in another product.

In addition, the development of functioning software, the Calendar Tool focuses on two additional problems not addressed in commercial tools:

  1. to provide a pedagogical example for use in the instruction of software engineering, including an example of the practical application of formal methods

  2. to provide fully documented, public domain source code for use by others
