The Business Problem:

Note: There are many details missing from the casefeel free to make assumptions (but please state them) and be innovative.

Torkore Inc. (TI), a leading manufacturing company, recently purchased the Softrip system, an of- the-shelf package, to implement a streamlined process supporting employee travel requirements in the company. The main focus of the implementation is on authorizing travel and reporting expenses.

When an employee identifies a travel need, he uses Softrip to prepare a travel authorization request. The request specifies the destination(s) and the justification for the travel and an expense estimate for the trip in broad categories (air travel, ground transportation, meals, lodging, meeting fees, etc.). Once the employee has completed the request, he submits it through the system. The request is received first by the travel office, which will review it for technical correctness. If it is not technically correct, it will be sent back to the employee for review and resubmission. If the travel office finds no technical errors, the request will next move to the employees immediate supervisor for his approval. If the amount of the requested travel expense exceeds an annually set limit, the authorization request will go to the divisional manager for additional review. If either the supervisor or the divisional manager rejects the request, they will inform the travel office and ask them to send a note of rejection with a justification to the employee.

If, however, the authorization is accepted, the employee will move forward to book their travel. The actual travel booking is outside this process description but any expense incurred before the travel (such as flight reservation or prepaid hotel) needs to be recorded with the system. Once the trip has commenced, the same process continues: the employee can use a mobile device to specify travel expense details and submit them with an image of the relevant receipts. These process steps will be repeated as long as there are additional expenses to record.

After the trip has ended, the employee has up to two weeks to complete a final travel report. During this process, the employee may enter, timestamp, and justify new expenses and revise those submitted earlier in the process. Once the report is ready, the employee submits it using the system, which sends it to the travel office for technical review. If the travel office rejects the submission, the report is returned to the employee with clarifying questions. If the travel office accepts it, it will be sent to both the supervisor and the divisional manager simultaneously for approval. Only after both have responded will the travel office integrate the results. If they dont raise concerns, the travel report review results are sent to the employee for his final review. However, if there are concerns, the travel office initiates a formal expense review. The review itself is outside the scope of the regular travel process.
