Gantt Chart See bar chart. ( Reference : PMI:PMBOK)
General system characteristics (GSCs) The general system characteristics are a set of 14 questions that evaluate the overall complexity of the application. ( Reference : IFPUG CPM 4.1)
General Systems Characteristics Fourteen quality and technical features identified to be delivered with the functions of the software. The 14 characteristics (GSCís) or features are assessed for their degree of influence on the software application as a whole and for their impact on the development and maintenance activities for the software. Albrechtís algorithm (VAF = 0.65 + [0.01 * Sum GSCís]) is used to calculate the Value Adjustment Factor for the software. ( Reference : Total Metrics)
generic practice An implementation or institutionalization practice that enhances the capability to perform any process. Generic practices are used during process appraisals to determine capability in any process area. [Jones - Loral FS] ( Reference : SEI:SE-CMM)
goals The aggregate result achieved by the effective implementation of the common features of a key process area. The goals signify the scope and intent of each key process area. ( Reference : SEI:SA-CMM)
goals A summary of the key practices of a key process area that can be used to determine whether an organization or project has effectively implemented the key process area. The goals signify the scope, boundaries, and intent of each key process area. ( Reference : SEI:SW-CMM)
grade an indicator or category or rank related to features or characteristics that cover different sets of needs for products or services intended for the same functional use ( Reference : TC176:8402)
grade category or rank given to the different quality requirements (4.1.9) for objects (4.1.6) having the same functional use EXAMPLE - Classes of airline ticket or categories of hotels in a hotel guide. NOTE - When planning the quality requirement (4.1.9) for an object (4.1.6), the grade for the quality requirement (4.1.9) must be known. ( Reference : TC176:ISO 9000:2000)
Graph Formally, a graph, G={V,E}, is composed of a set of vertices, V, and edges, E, connecting the vertices. Within the context of the CDIF presentation subject areas graphs are a grouping mechanism for Nodes and Edges. Usually Nodes correspond to vertices and Edges correspond to edges. ( Reference : ISO/IEC JTC1/SC7; CDIF:15474-1)
Graphical Evaluation and Review Technique (GERT) A network analysis technique that allows for conditional and probabilistic treatment of logical relationships (i.e., some activities may not be performed). ( Reference : PMI:PMBOK)
group An assemblage of personnel organized to serve a specific purpose or accomplish a task. A group may vary from a single individual assigned part time, to several part-time individuals assigned from other organizations, to several individuals dedicated full-time. ( Reference : SEI:SA-CMM)
group The collection of people who have responsibility for a set of tasks or activities. [Jones - Loral FS] ( Reference : SEI:SE-CMM)
group The collection of departments, managers, and individuals who have responsibility for a set of tasks or activities. A group could vary from a single individual assigned part time, to several part-time individuals assigned from different departments, to several individuals dedicated full time.
