Word scramble
Unscramble the letters and write each key term on the line.
1
SAYLSIAN
The first stage of the program development life cycle: identify the problem and list what the solution must do, using abstraction and decomposition, before any design starts.
2
SAIATRONCBT
Keeping only the detail that matters for the problem and hiding the rest, like a tube map showing stations and lines but not exact distances.
3
TACRSABT A ARINECSO
Read the scenario, list the details the solution needs and cross out the rest, saying 'because' for each choice (e.g. a bus app keeps times, not bus colour).
4
RCUUTSTRE RIADGMA
A diagram with the whole problem in a top box, joined by lines to lower boxes for each sub-problem, in levels. It shows the parts of the problem, not the order of the steps.
5
WTN-PODO EGIDSN
Name the whole problem in the top box, then split it into sub-problems level by level until each box is one simple task. Use clear box names.
6
TRHOFCWAL LBMOYS
A fixed shape showing one step in a flowchart: oval start/end, arrow flow, rectangle process, parallelogram input/output, diamond decision, double-sided rectangle subroutine.

1SAYLSIAN → analysis — The first stage of the program development life cycle: identify the problem and list what the solution must do, using abstraction and decomposition, before any design starts.
2SAIATRONCBT → abstraction — Keeping only the detail that matters for the problem and hiding the rest, like a tube map showing stations and lines but not exact distances.
3TACRSABT A ARINECSO → abstract a scenario — Read the scenario, list the details the solution needs and cross out the rest, saying 'because' for each choice (e.g. a bus app keeps times, not bus colour).
4RCUUTSTRE RIADGMA → structure diagram — A diagram with the whole problem in a top box, joined by lines to lower boxes for each sub-problem, in levels. It shows the parts of the problem, not the order of the steps.
5WTN-PODO EGIDSN → top-down design — Name the whole problem in the top box, then split it into sub-problems level by level until each box is one simple task. Use clear box names.
6TRHOFCWAL LBMOYS → flowchart symbol — A fixed shape showing one step in a flowchart: oval start/end, arrow flow, rectangle process, parallelogram input/output, diamond decision, double-sided rectangle subroutine.
