Editing Cost-effectiveness analysis (section)

===In military acquisitions===
In the acquisition of military [[tank]]s, for example, competing designs are compared not only for purchase price, but also for such factors as their operating [[radius]], top speed, [[rate of fire]], armor protection, and caliber and armor [[penetration (weapons)|penetration]] of their guns. If a tank's performance in these areas is equal or even slightly inferior to its competitor, but substantially less expensive and easier to produce, military planners may select it as more cost-effective than the competitor.

Conversely, if the difference in price is near zero, but the more costly competitor would convey an enormous battlefield advantage through special ammunition, [[radar]] [[fire-control system|fire control]] and [[laser]] [[range finding]], enabling it to destroy enemy tanks accurately at extreme ranges, military planners may choose it instead – based on the same cost-effectiveness principle.
