Onion Diagram
An onion diagram is a kind of chart that shows the Dependency (project management), dependencies among parts of an organization or process. The chart displays items in concentric circles, where the items in each ring depend on the items in the smaller rings. Information The onion diagram is able to show layers of a complete system in a few circles. Each of the circles is able to represent a component that is dependent upon the component on the inside of it shown by the circle inside of it. The main concept of the diagram is shown by the center circle of the diagram. This chart is used due to the fact that it has a clear visual representation that is easy to read, and it has a strong visual impact. Variations There is also the cultural onion which has seven layers to it including artifacts, behaviors, feelings, values, beliefs, worldview and ultimate allegiance. These layers organize a person's reality and life. The outer most layers are the most accessible while the in-depth ones ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chart
A chart (sometimes known as a graph) is a graphical representation for data visualization, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart". A chart can represent tabular numeric data, functions or some kinds of quality structure and provides different info. The term "chart" as a graphical representation of data has multiple meanings: * A data chart is a type of diagram or graph, that organizes and represents a set of numerical or qualitative data. * Maps that are adorned with extra information ( map surround) for a specific purpose are often known as charts, such as a nautical chart or aeronautical chart, typically spread over several map sheets. * Other domain-specific constructs are sometimes called charts, such as the chord chart in music notation or a record chart for album popularity. Charts are often used to ease understanding of large quantities of data and the relationships between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dependency (project Management)
In a project network, a dependency is a link among a project's terminal elements. The A Guide to the Project Management Body of Knowledge (PMBOK Guide) does not define the term dependency, but refers for this term to a logical relationship, which in turn is defined as ''dependency between two activities, or between an activity and a milestone''. Standard types of dependencies There are four standard types of dependencies: # Finish to start (FS) #* ''A'' FS ''B'' means "activity A must finish before activity B can begin" (or "B can't start until A has finished"). #* image:Dependency-FS.png #* ''(Foundations dug) FS (Concrete poured)'' # Finish to finish (FF) #* ''A'' FF ''B'' means "activity A must finish before activity B can finish" (or "B can't finish before A is finished") . #* image:Dependency-FF.png #* ''(Last chapter written) FF (Entire book written)'' # Start to start (SS). #* ''A'' SS ''B'' means "activity A must start before activity B can start" (or "B can't star ...

Onion Model
The onion model is a graph-based diagram and conceptual model for describing relationships among levels of a hierarchy, evoking a metaphor of the layered "shells" exposed when an onion (or other concentric assembly of spheroidal objects) is bisected by a plane that intersects the center or the innermost shell. The outer layers in the model typically add size and/or complexity, incrementally, around the inner layers they enclose. An onion diagram can be represented as an Euler or Venn diagram composed of a hierarchy of sets, A1...Ak (but perhaps potentially or conceptually infinite) where each set An+1 is a strict subset of An (and by recursion, of all Am where in each case m > n). (Some applications of the concept, however, may fail to benefit from the mathematical and otherwise rigorous properties of the model.) Such formats supported by Microsoft PowerPoint's SmartArt wizard invoke the term "stacked Venn". In computing The onion model in computing is used as a metaphor for t ...
