Executive Summary
This report is all about the principles of Software Engineering. Importance of software
development within an organization has been discussed here. An organization named as Hastings
dental health care has been taken into account and how this organization have used this newly
developed software for its betterment that has been described. Software development life cycle
along with all methods has been discussed and the challenges that need to be faced during a
software development, has been described. Finally, this report has been concluded that
importance of software development in an organization is very crucial for that overall
organizational development.

Part 1: Software design and project prototype
Use Case model
Actors and associations
There are 6 doctors in Hastings Dental Care House along with 2 administrators, 2 drivers,
reception staff and a manager. All the employees work on a full-time basis while the drivers
work as a freelance.

Use case Diagram
Class design
Class design is also known as structural diagram and provides the static layout of an application.
Class diagram is static in nature; it is applied in the visualization process, descriptions and
documenting of different aspects of a particular system along with the construction and
executing of codes of the application.
Class diagram defines the attributes and operation present in the class and the restriction
implemented the system (Jackson, 2017, p.185). Class diagrams are widely used in the designing
of object-oriented programming as they are the only UML diagrams that can be linked directly to
object-oriented systems.
