SESSION – 6 & 7 j , y Project: Time, Cost & Quality

Estimating Projects
• Estimating

• Types of Estimates
– Top-down (macro) estimates: analogy, group consensus, or mathematical relationships – Bottom-up (micro) estimates: estimates of elements of the work breakdown structure

Why Estimating Time and Cost Are Important
• Estimates are needed to support good decisions. • Estimates are needed to schedule work. • Estimates are needed to determine how long the project should take and its cost. • Estimates are needed to determine whether the project is worth doing. • Estimates are needed to develop cash flow needs. • Estimates are needed to determine how well the project is progressing. • Estimates are needed to develop time-phased budgets and establish the project baseline.

Estimating Guidelines for Times, Costs, and Resources
1. Have people familiar with the tasks make the estimate. 2. Use several people to make estimates. 3. Base estimates on normal conditions, efficient methods, and a normal level of resources. 4. Use consistent time units in estimating task times. 5. Treat each task as independent, don’t aggregate. 6. Don’t make allowances for contingencies. 7. Adding a risk assessment helps avoid surprises to stakeholders.

Macro versus Micro Estimating
Conditions for Preferring Top-Down or Bottom-up Time and Cost Estimates
Condition Strategic decision making Cost and time important High uncertainty Internal, small project Fixed-price contract

    Time, in project management, is analyzed down to its smallest detail. Cost over runs can be easily resolved in-house, but schedule issues are open and visible to the customer. Choices have to be made about which work to do and how to allocate resources. Which may lead to constraints specifically in regards to time constraint and the cost constraint? Every components of the project are analyzed on the basis to the time that is required for completion of the project. When completion of this analysis is met, the components are then broken down further into the time required to do each task. And out of all of this we will be able to estimate the duration of the project as well as what and how many/much resources need to be dedicated to that particular project. Costs are usually related to the resources which are required in the project. Cost of a project refers to what needs to be applied or assigned to the project in terms of effort and money in order to complete the project. This includes resources like materials, manpower or any third party resources that night need to be secured. However, when we allocate additional resources to the project we need to redesign the schedules which may lead to different critical paths and therefore, make it even more difficult to manage the project. In other words, we cannot change cost or time without…

    Agile estimation is defined as the, “quantified evaluation of the effort necessary to carry out a given development task” (Source). For Company X, estimation is done by asking the lead developer what their thoughts are for a story and assigning the provided number without any further conversation. At the end of sprints there is often work that is left uncompleted, due to inaccurate estimations. As a result, for the past 6 months Company X has exceeded their project budgets by over 175% and delivered work to their aligned business partners consistently behind schedule.…

    3. A mix of estimating techniques should be used in evaluating this project. As I stated in the previous answer – it’s important to have macro estimates in order to compare projects to one another. This allows management to weed out poor project choices without exhausting too much time or resources on gathering an estimate. On the other hand, after a project is selected for further development, a micro estimation needs to be done from the bottom up in order to fully understand all potential costs associated with the project. Proceeding with a project when all you have is a macro estimate is a risky move. That is why it is important to use both estimation techniques in the project selection…
