A time–distance diagram is a chart with two axes: one for time, the other for location. The units on either axis depend on the type of project: time can be expressed in minutes (for overnight construction of railroad modification projects such as the installation of switches) or years (for large construction projects); the location can be (kilo)meters, or other distinct units (such as ...
Waterfall charts can be used for various types of quantitative analysis, ranging from inventory analysis to performance analysis. [4] Waterfall charts are also commonly used in financial analysis to display how a net value is arrived at through gains and losses over time or between actual and budgeted amounts. Changes in cash flows or income ...
For example, it may be impossible to plan certain research projects far in advance, because research itself uncovers some opportunities (research paths) and actively eliminates others. However, another school of thought holds that all work can be planned, even if in weekly timeboxes or other short increments .
A Gantt chart is a type of bar chart [4] [5] that illustrates a project schedule. [6] This chart lists the tasks to be performed on the vertical axis, and time intervals on the horizontal axis. [ 4 ] [ 7 ] The width of the horizontal bars in the graph shows the duration of each activity.
Example from MIL-HDBK-881, which illustrates the first three levels of a typical aircraft system [1] A work-breakdown structure (WBS) [2] in project management and systems engineering is a deliverable-oriented breakdown of a project into smaller components. A work breakdown structure is a key project management element that organizes the team's ...
Project planning is part of project management, which relates to the use of schedules such as Gantt charts to plan and subsequently report progress within the project environment. [1] Project planning can be done manually or by the use of project management software. [2]
[6] [7] NASA, for example, uses quad charts to document the process of all Small Business Innovation Research projects. [8] Because decision makers often review a large volume of both solicited and unsolicited proposals, the quad chart may be the only submission from a potential contractor which the decision maker actually reads.
The radar chart is a chart and/or plot that consists of a sequence of equi-angular spokes, called radii, with each spoke representing one of the variables. The data length of a spoke is proportional to the magnitude of the variable for the data point relative to the maximum magnitude of the variable across all data points.
