Presentations and talks
Adapt a presentation for listeners with different backgrounds
Pick the few terms your argument cannot work without and define each in a sentence or less, with an example. Put extra depth in an optional layer, such as a backup slide or a prepared answer, so newer listeners are not lost and experienced ones are not stalled.
Group A and what they already know: [ ] Group B and what they already know: [ ] Shared context all listeners need: [ ] Term or idea: [ ] Needed for the argument? [yes / no] One-sentence explanation: [ ] Example: [ ] Where in the talk it first appears: [ ] What experts can skip: [ ] Optional depth item: [ ] Where it lives: [backup slide / spoken answer / handout] Person I asked from Group A: [ ] Person I asked from Group B: [ ] What each said was unclear or slow: [ ]
Assumptions only some can follow
Read the draft as someone new to the field and mark every acronym, shortcut and unexplained step. Then read it as an expert and note any explanation that would feel condescending. Watch for a definition that relies on another unexplained term. Confirm each example is accurate and does not oversimplify into something wrong. Check that an explanation placed early still serves a listener who reaches a later slide, and that the optional depth is available without derailing the main line.
Read my draft twice, once as a complete newcomer and once as a specialist. List every assumption only one group could follow, including acronyms and skipped steps. Flag any definition that depends on another undefined term, and any example that oversimplifies into an inaccuracy.
Check with one person from each group
Ask one person from each background to hear the opening and the first definition. Ask the newcomer what stayed unclear and the expert whether any line felt slow. Adjust the wording and keep the optional material ready as backup slides or prepared answers. If you cannot reach real listeners, list the questions each group would likely ask and prepare answers.
