Work sampling is the statistical technique used for determining the proportion of time spent by workers in various defined categories of activity (e.g. setting up a machine, assembling two parts, idle…etc.). [1] It is as important as all other statistical techniques because it permits quick analysis, recognition, and enhancement of job ...
Activity-centered design (ACD) is an extension of the Human-centered design paradigm in interaction design. [1] ACD features heavier emphasis on the activities that a user would perform with a given piece of technology. ACD has its theoretical underpinnings in activity theory, [2] from which activities can be defined as actions taken by a user ...
Activity diagrams [1] are graphical representations of workflows of stepwise activities and actions [2] with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities.
Cultural-historical activity theory (CHAT) [1] is a theoretical framework [2] which helps to understand and analyse the relationship between the human mind (what people think and feel) and activity (what people do). [3][4][5] It traces its origins to the founders [6] of the cultural-historical school of Russian psychology L. S. Vygotsky [7] and ...
Active design. Active design is a set of building and planning principles that promote physical activity. [1] Active design in a building, landscape or city design integrates physical activity into the occupants' everyday routines, such as walking to the store or making a photocopy. [2] Active design involves urban planners, architects ...
The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
SADT basis element. Structured analysis and design technique (SADT) is a systems engineering and software engineering methodology for describing systems as a hierarchy of functions. SADT is a structured analysis modelling language, which uses two types of diagrams: activity models and data models. It was developed in the late 1960s by Douglas T ...
High-level design (HLD) explains the architecture that would be used to develop a system. The architecture diagram provides an overview of an entire system, identifying the main components that would be developed for the product and their interfaces. The HLD can use non-technical to mildly technical terms which should be understandable to the ...
