Question 1 Consider a project that you have a sufficient degree of experience with to generate an adequate time and cost estimate of. Pick something that has approximately 10-15 work packages and is complicated enough to require more than just human resources. Conduct two time and cost estimates for your project first using a top-down approach and then using a bottom-up approach. Compare the differences between your two time and cost estimates and reconcile the differences by highlighting the extra knowledge that you have included in your bottom-up estimate.
