Many of the activities within the package follow a similar structure:

First, the user is presented with a brief filling animation followed by a Main Menu from which he or she selects the topics they wish to study. The main topics are divided into categories depending on the types of fill to be delivered to the capsules. Other topics that have a bearing on the main sections (Defect Classification, Fault Diagnosis and Capsule Specifications) are housed as an addendum to the main categories.

When users first enter a main activity, they are given a brief introduction to the selected filling operation followed by a labelled diagrammatic representation of the filling machine. Selection of the 'Options' Menu will provide the user with a number of different operations (labels, the display of extra information, annotated or continuous animation) that can be performed on the schematic. Sometimes other buttons will be presented, offering alternative displays.

There are a few activities that do not follow exactly the general format. These include :

• About Filling Machines - gives a very brief overview of the processes involved in the filling of hard gelatin capsules.
  
• Capsule Specifications - a purely informational section that gives a summary of the standards required by the U.S. and British and European Pharmacopoeias.
  
• Defect Classification - outlines the different defects that can occur in capsules as a result of the filling.
  
• Fault Diagnosis - a diagnostic tool that specifies where and how specified capsule defects can occur in different makes of filling machine.

Each activity is only three to five screens long but is as interactive as possible. A large amount of information can be accessed from each screen; the user is in complete control of the package and dissemination of any of the information is entirely at his or her discretion. A map, enabling the user to jump directly between activities and a detailed glossary are also provided.
