Activity-based management focuses on managing activities to reduce costs and improve customer value. Kaplan and Cooper [1] divide ABM into operational and strategic: Operational ABM is about doing things right, using ABC information to improve efficiency. Those activities which add value to the product can be identified and improved.
Improving operational efficiency begins with measuring it. Since operational efficiency is about the output to input ratio, it must be measured on both the input and output side. Quite often, company management is measuring primarily on the input side, e.g., the unit production cost or the man hours required to produce one unit.
[25] [26] [27] In this case, with perfect competition in the output market the long-run equilibrium will involve all firms operating at the minimum point of their long-run average cost curves (i.e., at the borderline between economies and diseconomies of scale).
A complete compilation of cost-utility analyses in the peer-reviewed medical and public health literature is available from the Cost-Effectiveness Analysis Registry website. [ 6 ] A 1995 study of the cost-effectiveness of reviewed over 500 life-saving interventions found that the median cost-effectiveness was $42,000 per life-year saved. [ 7 ]
So, in the case of a cost-minimization problem, where the objective function coefficients represent the per-unit cost of the activities represented by the variables, the "reduced cost" coefficients indicate how much each cost coefficient would have to be reduced before the activity represented by the corresponding variable would be cost-effective.

Operational Excellence (OE) is the systematic implementation of principles and tools designed to enhance organizational performance, and create a culture focused on continuous improvement. It is intended to enable employees to identify, deliver, and enhance the flow of value to customers.
Every decision in the product development process affects cost: design is typically considered to account for 70–80% of the final cost of a project such as an engineering project [1] or the construction of a building. [2] In the public sector, cost reduction programs can be used where income is reduced or to reduce debt levels. [3]
