In order to elaborate the presented Interactive Model Architecture in detail, and further on to verify its correctness and flexibility, a series of prototypes is realized in IBM SmallTalk using IBM's graphical development environment VisualAge 2.0 [1].
The most recent prototype (PROTO-5) comprises the following processes [2]:
  • model setup;
  • saving of a model;
  • reloading from a saved model;
  • starting work orders;
  • scheduling work orders;
  • delegation of work orders;
  • duplication of work orders;
  • sending and receiving messages;
  • administration and query of data;
  • simple accommodation of the workplace setup;
  • selling conforming Product Market Mix definitions;
  • selling from stock on hand;
  • replenishing stocks;
  • defining product assortments;
  • defining Product Market Mix;
  • producing invoices;
  • sending invoices.
For the next prototype the following extensions are planned [3]:
  • flexible Workflow Management;
  • resource administration including personal preferences;
  • user type administration including authorization;
  • flexible workplace setup;
  • differentiated user views on domain objects.
All prototypes can be used for illustration purposes.

Notes:
[1] I reconstructed the latest version as PROTO-6.0.0 using VisualAge 6.0
[2] After the end of the IMA project in 1995, I created a new version PROTO6 without the retail and data processes .....
[3] ..... However, PROTO-6 partly contained the planned extensions, and is used for the chapter Illustrations
