Sequences and precise instructions

Be able to formulate a sequence of precise instructions that a machine can execute without interpretation, and identify when the order or clarity fails.

Everyday explanation

Imagine you are instructing a colleague who has never seen a coffee machine. If you say "press the start button" before you have said "fill it with water", the machine will run dry or the coffee will be water. A sequence is a list of steps in a specific order. Computers and machines follow instructions exactly as written. They do not guess. If a step is missing or out of order, the process stops or produces an incorrect result.

Intuition

For an instruction to work for a machine, three things are required:

  1. Precise – Use measurable values or specific actions. "Run the script" is better than "run that thing".
  2. In the right order – Prerequisites must be met before the next step. You cannot save a file before it is created.
  3. Complete – No implicit steps. The machine does not know what you are thinking. Every action must be explicit.

All programs, regardless of complexity, are fundamentally sequences of such precise instructions.

Mastery means

  • Structure instructions so the outcome is correct
  • Identify instructions that are missing or unclear
