Issues in Software Measurement & Estimation ISMA 2010
Measurement is a wonderful thing. However measurement without standards and definition can be worse than no measurement at all. This paper which I will be presenting at the 2010 ISMA conference begins the attack, highlighting the need and proposing that additional work commences in standards for estimation and measurement.

Heuristics for Systems Engineering Cost Estimation
Dr. Ricardo Valerdi of MIT sent me a pre-publication copy of his upcoming IEEE article. Here is the abstract:
“Engineering cannot wait until all phenomena are explained. Engineers may work effectively, often for centuries, with heuristics. This paper provides thirty one heuristics that have been inspired by the development and application of a systems engineering cost estimation model. The objective of this paper is to present such heuristics in a simple manner so that they can benefit systems engineering researchers and practitioners that develop, calibrate, and use cost models.”
I enjoyed the article (as I do with pretty much everything Ricardo produces). Such simple truths. A few heuristics quoted from the paper follow:
“Don’t assume the original statement of the problem is necessarily the best, or even the right one.”
“Let the available data drive the application boundaries of the model.”
“Design the rating scale according to the phenomenon being modeled.”
The full article is available, as provided by Ricardo here: “Heuristics for Systems Engineering Cost Estimation.”
