Part 3. Evaluation

Enterprise Architect is a CASE tool. In your own words and using examples, briefly describe what a CASE tool offers during analysis of the World-Wide Tours scenario, and what tasks the CASE tool supports. Give your own evaluation of how the role of an analyst/designer is supported by a CASE tool. Discuss how UML modelling supports the analyst/designer.

Functional Requirements

·Tours Manager – has overall responsibility and can carry out any Tour Leader’s duties in their

absence.

·Tour Leaders – are responsible for planning all aspects of specific tours. Each Tour Leader can lead several tours. A tour leader is responsible for pricing a tour so that it makes a small profit.

·Branch Manager – supervises a branch, and can carry out a Clerical Assistant’s duties. A branch

manager is responsible for balancing costs and receipts in their branch

·Team Administrator – supervises the headquarters tour support office, and can carry out a

Clerical Assistant’s duties

·Clerical Assistants – maintain all the basic records of tours, tour guides, drivers, venues, hotels, catering establishments, customer enquiries, bookings, invoices and payments. Clerical assistants can be found in branches as well as headquarters

·Finance Officer – is responsible for balancing costs and receipts overall

The main system tasks are:

·Clerical Assistants record new tours, itineraries and venues and can edit them if their details change. Clerical Assistants assign drivers to each tour, using information provided by the Tour Leader. This can happen when the tour record is created, or it may happen at a later time.

·Tour Leaders can view their own tours, and can make updates but not create new tour entries. Tour Leaders are responsible for adding itinerary and venue details on their tours and updating the cost estimate, either at the same time or separately. Clerical Assistants can also carry out these tasks using information provided by the Tour Leader

·Clerical Assistants record payments for customer bookings, both deposits and balances. The Tour Leader must check that all customers have paid in full before the start date of their tour.

·Clerical Assistants record new venue invoices. Tour Leader must approve each invoice on the system before it can be paid. The Tour Leader may update the tour cost estimate at the same time. Venue payments are sometimes required in advance; any advance payments in excess of

£1,500 must be approved (on the system) by the Finance Officer before the payment can be made.

·Payments are processed through a link to the separate accounting system. The new system will record payments for budget monitoring purposes, but other steps in processing the transaction (e.g. production of cheques) will be handled by the accounting system

·The Tour Management system will produce a variety of reports giving information on tour plans, budgets and spending to date. Tour Leaders can view these reports for their own tours; Branch Managers can view them for their own branches. The Tours Manager and Finance Officer can view them for all tours.
