Culture and group decision-making: two scenarios

Scenario one looks like a language problem and is really two problems wearing one coat. The comprehension issue and the gift-giving issue need separating, because they call for opposite responses. Limited English affecting understanding of the task is something to solve — written summaries, confirming understanding rather than asking whether it is understood, pairing, allowing processing time — and it is a task risk. Gift-giving at the close of a project is a cultural practice, not a deficiency, and the right response is to understand what it means to the colleague and to check it against the organisation's own policy, not to correct it. Treating both as problems to be fixed is the most common misreading, and it is exactly the ethnocentrism the scenario is testing for. The prompt also asks what criteria you would set early, so the answer must include ground rules agreed at the start rather than remedies applied afterwards.

Scenario two hides a theory question in the middle of a practical one. How a group decision differs from an individual decision is asking about process gains and process losses — a wider information pool and better error-catching set against coordination cost, diffused responsibility, groupthink and social loafing, with the losses growing as the group grows. That is the substance of the argument for a smaller team, and it is far more persuasive to a manager than saying fifteen people feels like too many. On John, be careful to argue about behaviour and structure rather than about character: hidden agendas are managed by transparent decision criteria, documented rationale and clear role allocation, all of which work whether or not your read on him is correct. Recommending his exclusion on the basis of past impression is the trap here, and a marker reading for professional judgement will notice which way you went.
