You are asked to recommend which of two suppliers should provide a new IT service. One is cheaper, the other has a stronger track record on data security. Your manager needs a recommendation by the end of the day. Which response would be MOST effective?
- AAsk your manager to choose, because a decision with this much at stake should sit with someone more senior than you
- BRecommend the supplier with the stronger security record without setting out the reasoning, since the choice seems obvious
- CRecommend the cheaper supplier, because the department has been told to find savings and price is the easiest factor to defend
- DCompare both bids against the published criteria, weight security in line with the data involved, and recommend one with your reasoning set out✓
Answer: An effective decision is evidence-based and transparent: assess both bids against the agreed criteria, give security the weight the data warrants, and show your reasoning so the decision can be scrutinised. Choosing on price alone ignores a material risk, passing the decision upwards avoids the responsibility you were given, and a recommendation without reasoning cannot be checked or defended.
A colleague sends you a draft briefing that states a statistic you believe is out of date. The briefing is due with a senior official in an hour and your colleague is in a meeting. Which response would be MOST effective?
- ACheck the current figure against the official source, correct it if needed, and tell your colleague exactly what you changed and why✓
- BHold the briefing back until your colleague is free, since changing another person's work without asking would be discourteous
- CReplace the figure with your own estimate so the briefing goes out on time, and mention the change to your colleague later in the week
- DSend the briefing on time as it is, because the statistic is your colleague's responsibility rather than yours to alter
Answer: Getting the facts right matters more than ownership of the draft: verify the figure against the source, correct it, and be open with your colleague about the change. Sending a known error forward or substituting a guess both undermine the advice; holding the briefing back over etiquette misses the deadline for no good reason.
You are analysing responses to a public consultation. Most responses favour one option, but you notice that a large number are identical form letters from a single campaign. Which response would be MOST effective?
- ACount the campaign responses like the others, since each was submitted separately and the consultation's published terms set no rule against organised campaigns
- BReport the numbers honestly, distinguish the campaign responses from individual ones, and explain how each was weighed in the analysis✓
- CPresent the overall totals as one figure, because separating out the campaign responses might look as though the department is taking sides
- DExclude the campaign responses from the count so the analysis reflects the views of people who wrote in their own words
Answer: Objectivity means presenting the evidence as it is: show the totals, make the campaign responses visible as a distinct group, and be transparent about how they were treated. Counting them without comment or discarding them altogether both distort the picture, and hiding the distinction removes information decision-makers need.
Your team must decide quickly whether to pause a service after a report of a possible fault. The evidence is a single unverified complaint, but the potential harm if the fault is real is serious. Which response would be MOST effective?
- APause the service indefinitely straight away and wait for a full investigation to conclude before considering any restart
- BTake proportionate interim precautions now, verify the complaint urgently, and set a clear point at which the decision will be reviewed✓
- CAsk the complainant to provide proof of the fault before the team spends any time or resource looking into the report
- DKeep the service running unchanged until the complaint has been fully verified, since one report is not enough evidence to act on
Answer: When harm could be serious and the evidence is thin, the effective decision is proportionate: reduce the risk now, find out fast whether the fault is real, and commit to reviewing the decision. Doing nothing accepts a serious risk on the basis of convenience, an open-ended shutdown over-reacts to unverified evidence, and putting the burden of proof on the complainant delays the check that matters.
You have been given two weeks to review a policy and are offered a large amount of background reading. After the first few days you realise there is far more material than you can read in the time. Which response would be MOST effective?
- ASkim all of the material at speed so that you can say every source was considered, even if you retain little of the detail
- BIdentify the sources most relevant to the decision, prioritise those, and be clear in your review about what you did and did not cover✓
- CRead everything from start to finish even if the review is late, because a decision based on incomplete reading is not a proper decision
- DBase the review on the sources you have already read and leave the rest, without saying that the material was not all covered
Answer: Effective decisions are made with the best evidence available in the time, and are honest about their limits. Prioritising the relevant sources and stating what was not covered lets the reader judge the review. Missing the deadline, skimming without understanding, or quietly omitting material all weaken the advice.
You are drafting advice for a minister. Your own view is that one option is clearly best, but the evidence is genuinely mixed and a senior colleague favours a different option. Which response would be MOST effective?
- APresent only your preferred option so that the advice is clear and decisive rather than confusing the minister with a list of alternatives
- BPresent only the senior colleague's preferred option, because seniority should settle a disagreement about advice
- CSet out the options with the evidence for and against each, give a recommendation, and make clear where the evidence is uncertain✓
- DPresent the options without any recommendation at all, so that nobody in the team can later be blamed for whichever choice the minister makes
Answer: Civil servants give balanced, objective advice: the minister should see the realistic options, the evidence on each, and an honest recommendation that flags uncertainty. Narrowing the advice to one option - yours or a senior colleague's - removes the minister's choice, and withholding a recommendation avoids the job rather than doing it.
A decision you made last month, based on the information available then, has turned out badly because a key assumption proved wrong. Your manager asks what happened. Which response would be MOST effective?
- ASay as little as possible about the assumption, since the decision was reasonable at the time and dwelling on it helps nobody
- BExplain that the information you were given was inadequate, so responsibility for the outcome rests with those who supplied it
- CExplain the decision and the assumption openly, set out what has been learned, and propose what should change so the same gap is caught next time✓
- DOffer to reverse the decision immediately, whatever the cost, so that the department is seen to respond to the problem decisively
Answer: Owning a decision includes owning what went wrong with it: be open about the assumption, share the learning, and suggest a fix. Shifting responsibility to others or minimising the issue both damage trust, and a reflex reversal regardless of cost is a second poor decision rather than a remedy for the first.
Two members of your team disagree strongly about the right approach to a piece of analysis, and both have come to you to settle it. You do not yet understand the technical detail. Which response would be MOST effective?
- AChoose the approach of the more experienced team member, since experience is the most reliable guide when you cannot judge the detail
- BAsk each to set out their approach and evidence, test the reasoning with questions, and decide on the merits once you understand both✓
- CSplit the work so that each uses their own approach on half of the analysis, avoiding the need for you to rule either way
- DAsk the two of them to agree between themselves and come back only when they have a single approach to present to you
Answer: Deciding on the merits means understanding the arguments first: hear both approaches, probe them, and then choose. Deferring to seniority substitutes status for evidence, sending the disagreement back leaves it unresolved, and splitting the analysis two ways produces an inconsistent product to avoid a decision.
You must choose a venue for a public event at short notice. One venue is available immediately but has poor accessibility; a fully accessible one is available a week later. Which response would be MOST effective?
- ACancel the event, since neither option satisfies every requirement and a compromise would be criticised
- BChoose the venue available immediately, since meeting the original date is the priority and most attendees will not be affected by the access problems
- CChoose the accessible venue and adjust the date, unless the event genuinely cannot move, in which case put adjustments in place and document why✓
- DChoose the venue available immediately and offer to hold a separate session at an accessible venue later for anyone who could not attend the first
Answer: An effective decision weighs the legal duty to make services accessible against the timetable, and finds the option that meets both where possible. Prioritising the date over access, splitting attendees into two classes, or abandoning the event all decide badly.
You have to decide between two contractors' proposals. One scores higher on the published criteria; the other is preferred by a senior stakeholder who has worked with them before. Which response would be MOST effective?
- ARecommend the higher-scoring proposal and set out the scoring transparently, noting the stakeholder's view but not letting it override the criteria✓
- BRecommend the stakeholder's preferred contractor, since experience of working with a supplier is valuable and hard to score
- CRe-run the scoring with the stakeholder involved so that the criteria better reflect the value of prior experience
- DAsk the stakeholder to make the decision, since they are senior and will be accountable for the outcome
Answer: A decision made against published criteria must follow them, or the process is unfair to the other bidder and open to challenge. Overriding the scores, reshaping the criteria after the bids are in, or passing the decision to the interested party all compromise objectivity.
A colleague asks you to approve their expenses claim quickly because they are about to go on leave. One receipt is missing. Which response would be MOST effective?
- AApprove the items that are supported and ask for the missing receipt before approving that item, explaining why✓
- BApprove the whole claim and note in the system that a receipt is outstanding, so that finance can follow it up
- CApprove the whole claim now, since the colleague is trustworthy and the receipt can be added to the file later
- DRefuse the whole claim until every receipt is present, since the rules apply regardless of the colleague's leave
Answer: The effective decision applies the rule proportionately: approve what is evidenced, hold what is not, and explain. Approving unsupported items on trust, rejecting everything, or passing an incomplete claim to finance all get the balance wrong.
