Developments in Practice XXXVII: Total Cost of Ownership
Bibliographic record
Abstract
Total Cost of Ownership (TCO) advocates for a holistic view of IT costs across the enterprise over time, grouped into a series of direct and indirect cost elements. Knowing the full costs allows organizations to make optimal decisions regarding the enhancement, retirement, renewal, and/or replacement of critical IT assets. The authors convened a focus group of senior IT managers who were asked to describe their firm’s adoption of TCO, TCO processes, tools to assist with TCO implementations, the effectiveness of these tools, and the governance practices which guide their TCO processes. The group concluded that TCO, despite facing significant implementation challenges, remains a concept worth pursuing. This article reviews current literature, summarizes the focus group discussion, and offers practical guidance for those IT managers considering adopting TCO.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
