A Time-Driven Activity Cost Approach for the Reduction of Cost of IT Services: A Case Study in the Internet Service Industry
Bibliographic record
Abstract
This study aims to show that application of Time-Driven Activity Based Costing (TDABC) to the management of cost of Information Technology (IT) Services Operations and how it can be used to achieve significant cost reduction. To achieve this; a case study organization was used and the scope of activities was limited to Technical Services department Operations units. Interviews were conducted with the unit managers and their operations staff. From the interview, a list of services were developed and linked to activities and time to execute each was provided by the operational staff. Time equations were developed from the activity groups that supported each type of service. A TDABC model was then simulated with Microsoft Excel; which incorporated the activities, the time to deliver each and the capacity cost rate to derive the cost of delivering a service. The result of the test showed that two variations (out of six) of that incident type cost more than 75% of the overall cost of that incident type, though they constitute about 30% of the incident type. This study showed that TDABC is an effective tool in identification of costly processes which may then allow IT operations managers and supervisors to take critical decisions about cost control, charge-back or costing of services.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
