Where the C01 vocabulary sits, and how much of it is in each group — the 4 sections below follow the same order. Revise the heavy groups first.
Problem-solving methodology
Analysis stage
The stage of the problem-solving methodology where solution requirements, constraints and scope are determined
Design stage
The stage of the problem-solving methodology where the function and appearance of a solution are planned, and evaluation criteria created
Development stage
The stage of the problem-solving methodology where the solution is coded, validated, tested and documented
Evaluation stage
The stage of the problem-solving methodology where the completed solution is evaluated against the evaluation criteria and the project plan is assessed
Problem-solving methodology (PSM)
An approach that develops the stages involved in solving a problem
Design brief
Design brief
A document that identifies a problem, need or opportunity and describes the proposed software solution, its users, the programming language to be used, and how it is feasible and original
Feasibility
An assessment of whether a proposed solution is practical and achievable, commonly evaluated using the T.E.L.O.S. framework (Technical, Economic, Legal, Operational, Scheduling)
T.E.L.O.S.
A framework for assessing feasibility across five dimensions: Technical (can it be built?), Economic (can it be afforded?), Legal (is it lawful?), Operational (will it be used?), and Scheduling (can it be completed in time?)
Project management
Concepts (project management)
The milestones and dependencies within a project timeline
Concurrently
When a task is carried out at the same time as another task
Critical path
The shortest possible time in which a project can be completed
Dependency
A relationship between two tasks in a project plan where one task cannot begin until another has been completed
Predecessor
A task that must be completed before another one can be performed
Processes (project management)
Task identification, sequencing and allocation of time and resources within a project timeline
Project management
A method of recording the progress of a project and managing resources to operate within time, resource and cost availability
Slack time
The length of time that a task can run overtime before affecting other tasks
Successor
A task that must be completed after another task
Work breakdown structure (WBS)
An often hierarchical breakdown of a project that organises the work to be done into manageable sections, often displayed as a visual outline or map
Monitoring
The ongoing process of tracking a project's progress against the plan, identifying delays or changes, and documenting adjustments made
Gantt chart
Gantt chart
A type of bar chart or graphic timeline that shows the progress of a project by placing tasks on a timeline, often with comments or annotations
Milestone
A significant point or event in a project timeline that marks the completion of a key deliverable or the start of a new phase
