  5. Managerial role. A specific action or behavior expected of and exhibited by a manager.
  6. Universality of management. The reality that management is needed in all types and sizes of organizations, at all organizational levels, in all organizational areas, and in organizations no matter where located.
  7. Task. A single unit of work broken down from a user story. A task is usually completed by just one person.
    • Sprint task. A single small item of work that helps one particular story reach completion.
    • Task board. A physical or online visual representation of user stories broken down into tasks or work units. A physical task board can be as simple as a whiteboard with three columns labeled To Do, Doing, and Done; colored post-it notes or index cards representing tasks are placed in the column that reflects the task's current state. A task board can be expanded to hold more columns and can also include horizontal swim lanes.

Methods

  1. Disciplinary action. An action taken by a manager to enforce the organization's work standards and regulations.
  2. Schedule compression. A group of techniques used to shorten the schedule without reducing the scope. The compression is not always possible and often requires an increase in the cost.

Instruments

Results

  1. Operational plan. A plan that encompasses a particular operational area of the organization.
  2. Intention for bid (IFB). Communications, written or oral by the prospective sources showing their willingness to perform the specified work. This could be a letter, statement of qualifications or response to a request for proposal.

Practices

  • Contingency planning. The development of a management plan that identifies alternative strategies to be used to ensure project success if specified risk events occur.
  • Contract administration. Managing the relationship with the seller.
  • Contract closeout. Completion and settlement of the contract, including resolution of any open items.
  • Control. The process of comparing actual performance with planned performance, analyzing variances, evaluating possible alternatives, and taking appropriate corrective action as needed.
  • Control chart. A graphic display of the results, over time and against established control limits, of a process. They are used to determine if the process is "in control" or in need of adjustment.
  • Corrective action. Changes made to bring expected future performance of the project in line with the plan.
  • Cost budgeting. Allocating the cost estimates to individual work activities.
  • Cost estimating. Developing an approximation (estimate) of the cost of the resources needed to complete project activities.
  • Cost of quality. The costs incurred to ensure quality. The cost of quality includes quality planning, quality control, quality assurance, and rework.
  • Cost performance index (CPI). The cost efficiency ratio of earned value to actual costs. CPI is often used to predict the magnitude of a possible cost overrun using the following formula: BAC/CPI = projected cost at completion. CPI = EV divided by AC.
  • Cost-plus-fixed-fee contract (CPFF Contract). A type of contract where the buyer reimburses the seller for the seller's allowable costs (allowable costs are defined by the contract) plus a fixed amount of profit (fee).
  • Cost-plus-incentive-fee contract (CPIF Contract}. A type of contract where the buyer reimburses the seller for the seller's allowable costs (allowable costs are defined by the contract), and the seller earns its profit if it meets defined performance criteria.
  • Critical activity. Any activity on a critical path. Most commonly determined by using the critical path method. Although some activities are "critical," in the dictionary sense, without being on the critical path, this meaning is seldom used in the project context.
  • Critical path. The series of activities that determines the duration of the project. In a deterministic model, the critical path is usually defined as those activities with float less than or equal to a specified value, often zero. It is the longest path through the project. See critical path method.
  • Critical Path Method (CPM). A network analysis technique used to predict project duration by analyzing which sequence of activities (which path) has the least amount of scheduling flexibility (the least amount of float). Early dates are calculated by means of a forward pass, using a specified start date. Late dates are calculated by means of a backward pass, starting from a specified completion date (usually the forward pass' calculated project early finish date).
  • Data date (DD). The date at which, or up to which, the project's reporting system has provided actual status and accomplishments. Also called as-of date.
  • Decision tree analysis. The decision tree is a diagram that describes a decision under consideration and the implications of choosing one or another of the available alternatives. It incorporates probabilities or risks and the costs or rewards of each logical path of events and future decisions.
  • Deliverable. Any measurable, tangible, verifiable outcome, result, or item that must be produced to complete a project or part of a project. Often used more narrowly in reference to an external deliverable, which is a deliverable that is subject to approval by the project sponsor or customer.
  • Earned value (EV). The physical work accomplished plus the authorized budget for this work. The sum of the approved cost estimates (may include overhead allocation) for activities (or portions of activities) completed during a given period (usually project-to-date). Previously called the budgeted cost of work performed (BCWP) for an activity or group of activities.
  • Earned value management (EVM). A method for integrating scope, schedule, and resources, and for measuring project performance. It compares the amount of work that was planned with what was actually earned with what was actually spent to determine if cost and schedule performance are as planned.
  • Effort. The number of labor units required to complete an activity or other project element. Usually expressed as staff hours, staff days, or staff weeks. Should not be confused with duration.
  • Estimate. An assessment of the likely quantitative result. Usually applied to project costs and durations and should always include some indication of accuracy (e.g., ±x percent). Usually used with a modifier (e.g., preliminary, conceptual, feasibility). Some application areas have specific modifiers that imply particular accuracy ranges (e.g., order-of-magnitude estimate, budget estimate, and definitive estimate in engineering and construction projects).
  • Estimate at completion (EAC). The expected total cost of an activity, a group of activities, or the project when the defined scope of work has been completed. Most techniques for forecasting EAC include some adjustment of the original cost estimate, based on actual project performance to date.
  • Estimate to complete (ETC). The expected additional cost needed to complete an activity, a group of activities, or the project. Most techniques for forecasting ETC include some adjustment to the original estimate, based on project performance to date. Also called "estimated to complete." See also earned value and estimate at completion.
  • Exception report. Document that includes only major variations from plan (rather than all variations).
  • Firm fixed-price contract (FFP Contract). A type of contract where the buyer pays the seller a set amount (as defined by the contract), regardless of the seller's costs.
  • Fixed-price-incentive-fee contract (FPIF Contract). A type of contract where the buyer pays the seller a set amount (as defined by the contract), and the seller can earn an additional amount if it meets defined performance criteria.
  • Float. The amount of time that an activity may be delayed from its early start without delaying the project finish date. Float is a mathematical calculation, and can change as the project progresses and changes are made to the project plan. Also called slack, total float, and path float. See also free float.
  • Functional manager. A manager responsible for activities in a specialized department or function (e.g., engineering, manufacturing, marketing).

  • Grade. A category or rank used to distinguish items that have the same functional use (e.g., "hammer"), but do not share the same requirements for quality (e.g., different hammers may need to withstand different amounts of force).
  • Information distribution. Making needed information available to project stakeholders in a timely manner.
  • Initiation. Authorizing the project or phase.
  • Invitation for bid (IFB). Generally, this term is equivalent to request for proposal. However, in some application areas, it may have a narrower or more specific meaning.
  • Lag. A modification of a logical relationship that directs a delay in the successor task. For example, in a finish-to-start dependency with a ten-day lag, the successor activity cannot start until ten days after the predecessor has finished. See also lead.
  • Lead. A modification of a logical relationship that allows an acceleration of the successor task. For example, in a finish-to-start dependency with a ten-day lead, the successor activity can start ten days before the predecessor has finished. See also lag.
  • Level of effort (LOE). Support-type activity (e.g., vendor or customer liaison) that does not readily lend itself to measurement of discrete accomplishment. It is generally characterized by a uniform rate of activity over a period of time determined by the activities it supports.
  • Life-cycle costing. The concept of including acquisition, operating, and disposal costs when evaluating various alternatives.
  • Line manager. (1) The manager of any group that actually makes a product or performs a service. (2) A functional manager.
  • Logical relationship. A dependency between two project activities, or between a project activity and a milestone. See also precedence relationship. The four possible types of logical relationships are: Finish-to-start — the initiation of work of the successor depends upon the completion of work of the predecessor. Finish-to-finish — the completion of the work of the successor cannot finish until the completion of work of the predecessor. Start-to-start — the initiation of work of the successor depends upon the initiation of the work of the predecessor. Start-to-finish — the completion of the successor is dependent upon the initiation of the predecessor.
