EVALUATION OF THE COST ESTIMATING PROCESS
AT WHITE SANDS MISSILE RANGE

EXECUTIVE SUMMARY
Currently, White Sands Missile Range cost estimates account for the majority of the labor, material, contracts, and equipment costs. Thus, on the basis cost alone, WSMRs cost estimating process must be carefully monitored and evaluated.
The problem in this study was to determine the options regarding improving the current cost estimating process. Specifically, my research included becoming a member of the Integrated Product Team focused on the Strategic Plan Initiative 1.1. My primary focus was determining the present level of the existing cost estimating tools. I compared what the Army, Navy, WSMR and NASA organizations were using and evaluated their performance to propose an effective cost estimating tool for the IPT to consider. Interviews with several Branch Chiefs familiar with cost estimating provided the principal data for this study.
Overall, nearly everyone I interviewed agreed upon the need of an effective tool that would provide a system for managing project costs, measuring earned value, analyzing budgets, actuals and projections. However, I found that everyone has their own method of doing cost estimates and how they are archiving them.
During my investigation I found forty-five existing cost estimating methods and narrowed it down to a list of five. I selected the five best that fit the needs of what the IPT was looking for. I evaluated each of their strengths and weaknesses. Therefore, I recommend that WSTC should consider further study of the methods I found to improve its current cost estimating process. In the meantime, I continue to work with the IPT in the development of an effective cost estimating tool that meets the requirements of Initiative 1.1.

EVALUATION OF THE COST ESTIMATING PROCESS
AT WHITE SANDS MISSILE RANGE

INTRODUCTION
Cost estimates are a rapidly growing and increasingly important factor in the future success of White Sands Missile Range. Without an effective way of cost estimating your chances of retaining current customers is dismal. However, by analyzing methods to improve cost estimates we can improve our processes and grow to be a striving organization.
This study inspired me to become a member of the IPT focused on Initiative 1.1 outlined in the 2004 WSMR Strategic Plan. Our goal as a team is to develop a coordinated cost estimating process and tool for the White Sands Test Center (WSTC). As part of my study I wanted to take a look at the current cost estimating process and how it works. As a result, I found that our process accounts for the majority of labor, material, contracts and equipment costs. Thus, on the basis of cost alone, our process must be carefully monitored and evaluated.
In addition, I compared what the Army, Navy, and NASA are using to create accurate cost estimates against what we are using. Primarily, I used the results as the basis of improving our methods.
PURPOSE AND SCOPE OF THE STUDY
The purpose of this study is to inform and propose an effective cost estimating process and tool for the IPT to implement. This will help ensure that our current business will be retained and provide outstanding customer satisfaction. Our team goal is to provide a tool that would give customers timely and accurate cost estimates, track costs and deliverables, and integrate it with all WSTC Directorate requirements. Specifically, the following was addressed
in this study: Will this cost estimating tool provide a system for managing project costs, measuring earned value, analyze budgets, actuals and projections? To answer this question, I had to address the following:
If my actuals are less than what we budgeted. Does it mean our project is doing well or are we behind schedule?
What will it cost to finish the project, and is it within budget?
What factors are causing our cost variance?
This study explored the effects of our responsiveness to customer requirements. I found that our responsiveness to our customers needs improvement. In addition, we need a process that simplifies and speeds up the estimating process while increasing our accuracy.
Further study indicated that the Army Test and Evaluation Command (ATEC) encourage the use of Microsoft Project and Earned Value calculations as a source of cost estimating within the Department of Defense (DOD). Therefore, I evaluated the options in which MS Project and the earned value methods were incorporated.
Today, WSMR has no existing tools that collaborate with MS Project or earned value calculations. Currently, the majority of our customers are already using both of these methods in their cost estimates. This study
