Accurately estimating the level of effort required to deliver a project is one of the most important aspects of successful project management. Poor estimates can lead to missed deadlines, budget overruns, resource conflicts, and reduced customer satisfaction. For Professional Services Organisations (PSOs), consulting firms, software development teams, and enterprise PMOs, having a structured estimation framework is essential to improving project predictability and profitability.
The PERT Estimator within Mission Control provides organisations with a collaborative and structured approach to estimating work effort directly within Salesforce. By enabling multiple team members to contribute estimates using the Program Evaluation Review Technique (PERT), Mission Control helps businesses create more accurate project forecasts while reducing the risk of underestimating or overestimating work.
The PERT Estimator feature streamlines the entire estimation lifecycle, from requesting estimates from subject matter experts through to reviewing and finalising agreed project estimates. Whether you are managing agile software development projects, consulting engagements, customer onboarding programs, or enterprise transformation initiatives, the PERT Estimator ensures your teams can make informed planning decisions with greater confidence.
What is the PERT Estimator in Mission Control?
The PERT Estimator in Mission Control is a collaborative estimation framework that enables teams to assess the effort required to complete work items such as Actions and Requirements. It is designed to help organisations improve project planning accuracy by gathering multiple perspectives from stakeholders, resources, and delivery teams.
PERT estimation uses three separate estimate values to calculate a weighted average estimate:
- Optimistic Estimate
- Most Likely Estimate
- Pessimistic Estimate
The final PERT Estimate is calculated using the following formula:
(Optimistic Estimate + 4(Most Likely Estimate) + Pessimistic Estimate) / 6
This weighted approach provides a more realistic estimate by giving greater emphasis to the “Most Likely” scenario whilst still accounting for best-case and worst-case outcomes. By using this methodology, project managers can significantly improve forecasting accuracy and reduce uncertainty during project planning.
Within Mission Control, the PERT estimating process is completed in three structured stages. First, project managers request estimates from specific Roles. Second, individual estimators complete their estimates using the Estimating Wizard. Finally, reviewers assess all submitted estimates and finalise the agreed PERT Estimate for the work item. This process creates transparency, accountability, and consistency across project estimation activities.
Because the PERT Estimator is built natively on the Salesforce Platform, all estimation data sits alongside your broader project management information. This means teams can seamlessly connect estimation activities with project scheduling, resource management, financial forecasting, sprint planning, and reporting without relying on disconnected spreadsheets or third-party tools.
The feature is especially valuable for organisations delivering complex projects involving multiple teams or specialised skill sets. By allowing several estimators to contribute their perspectives, businesses can avoid relying on a single individual’s assumptions and instead create balanced, data-driven estimates that improve project outcomes.
Key Features of the PERT Estimator in Mission Control
One of the most powerful aspects of the PERT Estimator is the ability to request estimates from multiple Roles across Programs, Projects, and Milestones. Using the Request Estimates Component, project managers can quickly determine which Actions or Requirements require estimates and assign the appropriate estimators to each piece of work.
Project managers can select estimators individually or automatically include Roles based on ownership criteria such as:
- Action Owners
- Action Owners & Contributors
- Action Owners & Checklist Item Owners
This flexibility ensures the right people are involved in the estimation process and allows organisations to leverage the expertise of subject matter specialists across various departments or delivery teams.
The Estimating Wizard provides a highly intuitive workspace where individual estimators can complete their estimates efficiently. The workspace includes detailed contextual information relating to the work item being estimated, ensuring estimators have visibility into project requirements, acceptance criteria, dependencies, and related records before providing their estimates.
The PERT Estimator also supports related record estimation. For example, if an Action or Requirement contains User Stories or Checklist Items, estimators can create detailed estimates for each related item individually. Mission Control will then automatically calculate a summary PERT Estimate based on all underlying estimates. This granular estimation capability is particularly valuable for agile delivery teams managing complex sprint planning activities.
Another major benefit of the PERT Estimator is Reviewer Mode. Senior project managers, PMO leaders, or designated reviewers can analyse all submitted estimates in a collaborative review workspace. Reviewers can include or exclude individual estimates, compare variations between estimators, and finalise the agreed PERT Estimate directly against the Action or Requirement.
Reviewer Mode can be configured with different access permissions, including:
- All Records
- My Records
This ensures businesses maintain appropriate governance and security controls while enabling estimation oversight across multiple projects and programs.
Mission Control also improves visibility through Daily Digest notifications. Team members automatically receive summaries of overdue estimates, estimates to complete, and estimates awaiting review. These proactive reminders help organisations keep estimation activities moving efficiently and reduce delays during project initiation and sprint planning.
Another standout feature is the flexibility available through Salesforce Field Sets. Businesses can configure which fields appear within the Estimating Wizard, ensuring estimators have access to the exact information required for accurate decision-making. This level of customisation enables organisations to tailor the estimation experience to their own project delivery methodology.
How to use the PERT Estimator in Mission Control
Using the PERT Estimator in Mission Control begins with creating estimate requests. Project managers can access the Request Estimates Component from Program, Project, or Milestone records. From here, they can select whether they wish to display Actions, Requirements, or both.
Once the relevant records are displayed, project managers can assign estimators using the Add Estimators section. Multiple Roles can be assigned to individual pieces of work, ensuring a broad range of expertise contributes to the final estimate. Due dates can also be assigned to help keep the estimation process on track.
After saving the requests, individual Estimate records are automatically created for each assigned estimator. Project managers can then monitor progress directly from the Request Estimates Component, providing complete visibility into which estimates are in Draft, Submitted, or overdue status.
Estimators complete their work using the Estimating Wizard. This component provides a centralised workspace where users can review the details of the work item and enter their Optimistic, Most Likely, and Pessimistic Estimates. As the values are entered, Mission Control automatically calculates the PERT Estimate.
If required, estimators can save their work in Draft status while continuing to refine their estimates. Once complete, they can submit the estimate for review. Submitted estimates become locked to maintain data integrity, though users can recall estimates if updates are required later.
For organisations using agile project management methodologies, the Related Information section is particularly valuable. Estimators can break work down into smaller User Stories or Checklist Items and estimate each item individually. The combined estimates can then be rolled up into the primary estimate automatically, improving estimation accuracy for large or complex initiatives.
The final stage of the process involves the Reviewer Mode within the Estimating Wizard. Reviewers can evaluate all submitted estimates side by side, compare estimation differences, and discuss assumptions with delivery teams. Individual estimates can be excluded where necessary, allowing reviewers to remove outliers or inaccurate submissions from the final calculation.
Once the final estimate has been agreed upon, the reviewer manually enters the final PERT Estimate and Hours Scheduled values directly against the Action or Requirement. These figures then become part of the broader project plan, supporting downstream scheduling, resource allocation, financial forecasting, and delivery reporting activities.
Because the PERT Estimator is fully integrated into Mission Control’s Salesforce-native PSA platform, the final estimates seamlessly connect with other project management processes including sprint planning, resource forecasting, budget management, and utilisation reporting.
