Developing the schedule
Term | Definition |
---|---|
Critical chain | A networking technique that identifies paths through a project based on resource dependencies, as well as technical dependencies. |
Critical path | A sequence of activities through a network diagram from start to finish, the sum of whose durations determines the overall duration. There may be more than one such path. |
Finish-to-finish | A dependency in an activity-on-node network. It indicates that one activity cannot finish until another activity has finished. |
Finish-to-start | A dependency in an activity-on-node network. It indicates that one activity cannot start until another activity has finished. |
Schedule management | The process of developing, maintaining and communicating schedules for time and resource. |
Start-to-finish | A dependency in an activity-on-node network. It indicates that one activity cannot finish until another activity has started. |
Consumable resource | A type of resource that only remains available until consumed (for example a material). |
Resource allocation | The process by which resources are attributed to activities. |
Resource availability | The level of availability of a resource, which may vary over time. |
Resource levelling | A scheduling calculation that delays activities such that resource usage is kept below specified limits. It is also known as resource limited scheduling. |
Resource management | The acquisition and deployment of the internal and external resources required to deliver the project, programme or portfolio. |
Resource scheduling | A collection of techniques used to calculate the resources required to deliver the work and when they will be required. |
Resource smoothing | A scheduling calculation that involves utilising float or increasing or decreasing the resources required for specific activities, such that any peaks and troughs of resource usage are smoothed out. |
Resources | All those items required to undertake work including people, finance and materials. |
Re-usable resource | A resource that when no longer needed becomes available for other uses. Accommodation, machines, test equipment and people are re-usable. |
Schedule | A timetable showing the forecast start and finish dates for activities or events within a project, programme or portfolio. |
Start-to-start | A dependency in an activity-on-node network. It indicates that one activity cannot start until another activity has started. |
Three-point estimate | An estimate in which the most likely mid-range value, an optimistic value and a pessimistic, worst case value are given. |
Time boxing | The production of project deliverables in circumstances where time and resources including funding are fixed and the requirements are prioritised and vary depending on what can be achieved in the time box. |
Time chainage | A form of graphical schedule that shows activity in relation to physical location as well as time. |
Time driven | Control actions or reports that are triggered by the passage of a defined interval (e.g. monthly) are referred to as ‘time-driven’. |
Time scheduling | A collection of techniques used to develop and present schedules that show when work will be performed. |
Total float | Time by which an activity may be delayed or extended without affecting the overall duration or violating a target finish date. |
Budgeting and cost control | The estimation of costs, the setting of an agreed budget, and management of actual and forecast costs against that budget |
Committed expenditure | Costs that have not yet been paid but cannot be cancelled. |
Drawdown | The removal of funds from an agreed source resulting in a reduction of available funds. |
Funding | The means by which the capital required to undertake a project, programme or portfolio is secured and then made available as required. |
Management reserve | A sum of money held as an overall contingency to cover the cost impact of some unexpected event. |
