1. Faster Cost Estimate Convergence with SLOC-Check

2. Cone of Uncertainty In Cost Estimation
Ainsley Chong

3. Why are Cost Estimates not Revisited?
Cost estimation is complicated
Cost estimation is time consuming
The project manager does not know what is happening at the coding level
Ainsley Chong

4. What are Cost Estimates Used For?
Unfortunately: Project Proposal Tool
Ideally: Project Management Tool
Ainsley Chong

5. SLOC-Check Concept: Goals:
An online tool that allows project managers and developers to quickly exchange information about the estimated size of the code (SLOC)
Goals:
Create “early warnings” when a estimate is no longer accurate
Provide project managers developers better information about the state of the project
Provide transparency to developers about project manager expectations
Lightweight: should be easy to implement, and only take about 5 minutes of extra time per developer, per week

9. SLOC-Check: Summary Report

10. Summary
SLOC-Check will provide a quick way for project managers and developers to exchange information about the current state of the project
Better information will lead to better estimates, and thus earlier detection of problems in the project
