Systems Analysis, Design, Testing, and Implementation Vocabulary

Vocabulary flashcards covering key ICT concepts including research methods, system design, testing strategies, implementation types, verification, and validation techniques.

Test Strategy

A document describing the overall testing approach of a system, mapping out test designs, methods, and techniques before a test plan is created.

Test Plan

A document detailing the specific tests to be carried out on a piece of software, showing test objectives and describing how, when, and by whom testing will be performed.

Visual Verification

A verification method where entered data is visually compared against the original source document to check for copy or transcription errors.

Parallel Running

An implementation method where the old system and new system operate together until the new system is proven to work properly, after which the old system is removed.

Direct Changeover

An implementation method where the old system is stopped completely and replaced immediately by the new system on a specific date.

Pilot Changeover

An implementation method where the new system is fully implemented in one branch or location at a time to test performance before expanding to others.

Phased Implementation

An implementation method where a new system is introduced into an organization one module or process at a time.

System Specification

A document created during system analysis that outlines general requirements, system capabilities, and recommended hardware and software specs.

Normal Test Data

Test data that falls within the acceptable bounds and represents typical, valid inputs expected by the software.

Extreme Test Data

Test data that lies on the extreme boundary limits of acceptable values for a system.

Abnormal Test Data

Test data outside acceptable limits or in an incorrect format that the system should reject.

Technical Documentation

System documentation created for programmers, analysts, and developers to assist with maintaining, updating, and repairing the software system.

User Documentation

Documentation produced to help end-users learn how to operate, navigate, and troubleshoot a computer program.

Observation

A research method where an analyst watches people use an existing system to identify inputs, processes, outputs, and errors.

Interview

A face-to-face, one-to-one research method between an analyst and an employee to gather detailed qualitative information.

Questionnaire

A research method involving written questions given to multiple users, allowing fast, low-cost, anonymous data collection.

Format Check

A validation check that verifies whether input data matches a specified template or pattern, such as dd/mm/yyyy.

Range Check

A validation check that ensures input data falls within specified minimum and maximum numerical or date boundaries.

Length Check

A validation check that ensures input data contains a specific number of characters.

Character Check

A validation check that ensures input data contains only allowable characters or digits.

Type Check

A validation check that ensures data entered matches the designated data type, such as integer or text.

Presence Check

A validation check that ensures a field has not been left empty or submitted as a null value.

Check Digit

An extra digit appended to a numerical key, calculated from other digits, to verify data accuracy during entry.
