Word scramble
Unscramble the letters and write each key term on the line.
1
NEPSRGNIET A LPOPSAOR
Explain a proposal to its audience in plain language and logical order, using diagrams and justified decisions, then answer questions.
2
MTYESSS IITHKNNG
Seeing a solution as connected parts working together, and using a conceptual model to show those parts and their relationships before building anything.
3
METYSS RTOPIERPSE
The traits of a system as a whole: its purpose, its components and how they interact, and emergent behaviour that no single part has alone.
4
REUS TCFEEAINR
The part of a system where the user gives inputs and receives outputs. On a conceptual model it sits on the system boundary as the link between the user and the system.
5
YESTSM LRNTOCO
A mechanism, such as input validation, user feedback or access limits, that keeps a system's behaviour within what is intended.
6
EMFWAEIRR
A simple, mostly greyscale layout of a screen showing where content and controls sit, using placeholder boxes and no colour, images or final styling.
7
ELRAT EALBT
An SQL command that changes the structure of an existing table, such as adding, modifying or dropping a column. Existing rows are kept, and a new column is empty (NULL) for them.
8
ODPR ABTLE
Permanently deletes a whole table, its structure and all its records. Unlike DELETE, which only removes rows, it cannot be undone and can fail if other tables reference it.
9
AIGVNH
Filters groups after GROUP BY using a condition on an aggregate, e.g. ______ COUNT(*) > 2. WHERE filters rows before grouping. ______ comes after GROUP BY.
10
IOSE.LCFEL()
Ends access to an open file so any written data is saved and the file is released. Forgetting it can lose data. A with statement closes the file for you automatically.
11
HILWE URTE:
Starts a menu loop that repeats forever: show options, read a choice, call the matching function with if/elif, reject invalid input, and break when the user picks quit.
12
ILIYRETAIBL
A solution is reliable when it behaves correctly and consistently every time it is used, even with invalid input or missing files or data. It handles errors without crashing.
13
UHTRCEISI WERIVE
Checking an existing interface against usability rules of thumb (e.g. Nielsen's heuristics), then recording each problem found with its severity and screen evidence.
14
XU QIIEURCT
A review of an existing interface that follows a user's path, judges how well it supports their goals using evidence, and recommends improvements.
15
IINSBLTISATAUY
How well a solution keeps meeting needs over time without unacceptable environmental, social or economic cost, such as energy use, running and update costs, and social impact.

1NEPSRGNIET A LPOPSAOR → Presenting a proposal — Explain a proposal to its audience in plain language and logical order, using diagrams and justified decisions, then answer questions.
2MTYESSS IITHKNNG → systems thinking — Seeing a solution as connected parts working together, and using a conceptual model to show those parts and their relationships before building anything.
3METYSS RTOPIERPSE → system properties — The traits of a system as a whole: its purpose, its components and how they interact, and emergent behaviour that no single part has alone.
4REUS TCFEEAINR → user interface — The part of a system where the user gives inputs and receives outputs. On a conceptual model it sits on the system boundary as the link between the user and the system.
5YESTSM LRNTOCO → system control — A mechanism, such as input validation, user feedback or access limits, that keeps a system's behaviour within what is intended.
6EMFWAEIRR → Wireframe — A simple, mostly greyscale layout of a screen showing where content and controls sit, using placeholder boxes and no colour, images or final styling.
7ELRAT EALBT → ALTER TABLE — An SQL command that changes the structure of an existing table, such as adding, modifying or dropping a column. Existing rows are kept, and a new column is empty (NULL) for them.
8ODPR ABTLE → DROP TABLE — Permanently deletes a whole table, its structure and all its records. Unlike DELETE, which only removes rows, it cannot be undone and can fail if other tables reference it.
9AIGVNH → HAVING — Filters groups after GROUP BY using a condition on an aggregate, e.g. HAVING COUNT(*) > 2. WHERE filters rows before grouping. HAVING comes after GROUP BY.
