  • A

  • Accept risk: Risk response strategy where we choose to take no preventative action if a risk occurs (no proactive response plan). We monitor the risk to see if actions need to be taken at a future time.

  • Acceptance criteria: Measurable "performance requirements and essential conditions which must be met before project deliverables are accepted." (definition from PMI)

  • Activities: The actual tasks or elements of work that must be done to produce the Work Package deliverable. Are sequenced.

  • Actual Cost (AC): Part of Earned Value Analysis. Based on your current progress to date, what did you actually spend by this time.

  • Analogous estimating: A "technique for estimating the duration or cost of an activity or a project using historical data from a similar activity or project" (definition from PMI). Requires obtaining historical data of similar projects.

  • Assumptions: Criteria or characteristics that are expected to be true about the project or its deliverables.

  • Avoid risk: Risk response strategy where we take preventative action to completely avoid the chance that the risk can occur.


  • B

  • Backward Pass: The process of moving from the finish of the network diagram, backwards through all the network paths towards the start of the diagram, to determine the latest start date and latest finish date for each activity and to determine float/slack.

  • Baseline: The Project Plan approved by key project stakeholders. Used during Execution to compare to actual project performance to determine if the project is on track (within approved variance limits). Can only be changed by an approved Change Order.

  • Bottom-up estimating: Estimates costs at the lowest level activities of the WBS, then costs are aggregated upwards to produce a total.

  • Budget at Completion (BAC): Part of Earned Value Analysis. Based on your original baselined plan, what you planned to spend to complete the entire project.

  • Business case: See "Purpose".


  • C

  • Change Control Board (CCB): A team of stakeholders that review and make decisions regarding changes that will or will not be made to the project.

  • Change control process: A process to manage changes to the baseline plan for scope, cost, or schedule. Change Orders are reviewed and either rejected or accepted (acceptance requires the Project Plan be changed and re-baselined)

  • Change Order/Change Request: "A formal proposal to modify any document, deliverable, or baseline." (definition from PMI) The proposal describes the change and impact, and must be reviewed and approved by a Change Control Board (CCB) before the change is enacted.

  • Closure (Phase): Last phase of the Project Life Cycle. Final deliverables and documentation are turned over the customer. A post project review is completed with best practices and lessons learned captured. The team celebrates/is recognized. Resources are reassigned to other projects.

  • Closure Plan: Documents the plan to Close the project. The plan is created in the Planning Phase so scope, schedule, budget, and resource needs can be documented.

  • Co-located team: Team members are in the same physical location. There is more opportunity for face-to-face communication.

  • Communication Plan: Documents the information that needs to be shared about the project, how often it will be shared, who it is shared with, the method used to share, and who's responsible for preparing and sharing that communication.

  • Constraints: Limits or restrictions that are known and must be accommodated during the project.

  • Contingency Budget/Funds: Additional money added to the budget to cover the cost of incurring potential risks that have been identified. Based on quantitative analysis of the risks and the risk tolerance of the organization.

  • Crashing: Schedule compression technique that adds resources or increases resource availability to critical activities to meet an accelerated schedule date.

  • Critical activities: All of the activities on the critical path. Cannot be started any earlier (ES=LS). Cannot be delayed without impacting the finish date of the project (EF=LF).

  • Critical path: The longest path through the network diagram in duration. Determines the critical activities.

  • Critical Path Method (CPM): "A method used to estimate the minimum project duration and determine the amount of scheduling flexibility on the logical network paths within the schedule model" (definition from PMI).

  • Estimate to Complete (ETC): The money required to complete the remaining work on our project. ETC = (BAC - EV) ÷ CPI

  • Exclusions: Features, functions, services, or deliverables that are not included in the scope of work or project objectives or deemed to be covered by resources outside of the project.

  • Execution (Phase): Third phase of the Project Life Cycle. Work is performed to complete the project deliverable. The project is monitored and controlled (adjusted) to ensure that the actual work being delivered meets the scope, cost, and schedule documented in the Project Plan. Regular team meetings happen and status updates are shared with stakeholders.

  • Expected Monetary Value (EMV): Takes the probability of occurrence of a risk (as a percentage) multiplied by the monetary value of the impact (cost impact if the risk happens), to get a value that is added to contingency funds.


  • F

  • Fast Tracking: A schedule compression technique that reduces the duration of a critical path by partially or fully overlapping the activities (changing the sequence to make the activities run in parallel or overlap rather than in sequence).

  • Process: An operation performed repeatedly to sustain the business (no defined start or end).

  • Procurement Plan: Documents the process that will be used to engage suppliers, contract with suppliers, and manage the supplier relationship.

  • Profitability Index: A financial measure for selecting projects. Similar to NPV, but expressed as a ratio. If the ratio is greater than 1, there will be financial benefits (the larger the number, the greater the benefit).

  • Q

  • Quality audit: "A structured, independent process to determine if project activities comply with organizational and project policies, processes, and procedures" (definition from PMI). A review of the processes used on a project to identify improvements and efficiencies. May also be referred to as a Project Health Check.

  • Resource leveling: "A technique in which start and finish dates are adjusted based on resource constraints with the goal of balancing demand for resources with the available supply" (definition from PMI). Changes the schedule to shift activities to fit when resources are available (resolves resource overallocation/constrained resources but likely elongates the project).

  • Resource smoothing: "A technique which adjusts the activities of a schedule model such that the requirement for resources on the project do not exceed certain predefined resource limits" (definition from PMI). Uses available float to shift activities to smooth out resource usage (helps resolve some resource overallocation/constrained resources without elongating the project).
