Write an Executive Memo Recommending a Product Launch Decision

The phased recommendation is well supported by beta performance, the 70% Engineering estimate, incomplete training, and the absence of May 6-linked contracts. However, the memo incorrectly describes May 24 as preceding May 20 general availability and misleadingly frames the $35,000 campaign-change cost as a drawback of a full delay rather than a likely consideration for revised phased-launch messaging as well.

The recommendation and rationale are direct, and confirmed facts are generally distinguished from Engineering's 70% estimate. Clarity is undermined by the explicit chronological contradiction that May 24 is prior to May 20 and by ambiguity over whether the $35,000 campaign cost applies to the phased option.

The subject line, situation summary, recommendation, rationale, numbered risks, and approval requests create a highly scannable decision memo. It is concise and appears to remain near the requested 400–550-word range without excessive repetition.

The committee is asked to approve exact access groups and dates, accept identified risks, and direct Marketing to act by April 29. The requests would be stronger if they explicitly sought approval for the campaign-change spending and established a readiness condition or review before May 20, especially because security resolution is not expected until May 24.

The tone is calm, candid, professional, and non-blaming. It communicates uncertainty plainly and uses language suited to executive decision-makers, though the final offer to walk through the facts is somewhat unnecessary.

Answer A makes a clear, defensible recommendation grounded entirely in the supplied facts. It prioritizes material considerations and avoids inventing any details, strictly adhering to the prompt's constraints.

The memo is easy to scan, concise, and clearly distinguishes confirmed facts from forecasts. It is understandable to a nontechnical executive audience.

The memo follows a logical structure with clear headings for situation summary, recommendation, rationale, risks, and decisions needed, as requested by the prompt.

Answer A identifies practical mitigations for each risk and ends with precise, actionable requests for committee approval, including a specific directive for Marketing with a deadline.

The tone is consistently calm, candid, and professional throughout the memo, without assigning blame to any team.

Answer A stays faithful to the supplied facts, correctly attributes estimates (70% confidence, $35,000 Finance estimate), distinguishes confirmed facts from forecasts, and makes a defensible phased-launch recommendation. Its only slip is stating the May 24 security resolution occurs 'prior to general availability' when GA is May 20 — a small but real inconsistency. Otherwise it fits the executive audience and the decision deadline precisely.

Answer A is easy to scan for nontechnical executives: clean capitalized headers, numbered risks each paired with a mitigation, and a subject line that embeds the April 29 deadline. Sentences are direct and estimates are clearly labeled as such.

Answer A follows the required memo architecture exactly: subject line with deadline, situation summary, recommendation, rationale, enumerated risks with mitigations, and a numbered approvals section. Information flows logically toward the decision request with no redundancy.

Answer A ends with precise, executable requests: approve the specific phase dates, explicitly accept named risks (the 70% fix confidence and temporary security mitigations pending May 24), and direct Marketing to revise messaging by April 29. The decision deadline is surfaced in the subject line, giving the committee everything needed to act immediately.

Answer A is calm, candid, and blame-free. It acknowledges uncertainty openly (70% confidence, pending load test) without alarmism, credits teams neutrally, and closes with a professional offer to brief the committee.

The central recommendation fits the facts, but several details are inaccurate or invented. The answer reverses the security facts by saying temporary mitigation is expected by May 24 and permanent resolution later, adds an unsupported 2024 date, states that Engineering is prioritizing the patch, and speculates about the cost of a failed launch.

The prose is generally understandable to nontechnical executives and the recommendation is repeated clearly. However, the inaccurate security timeline and vague claims such as minimizing disruption and enabling rapid iteration make the risk picture less clear than it should be.

The memo uses appropriate headings and a conventional executive format, but it repeats the situation and recommendation across multiple sections and appears substantially longer than the 550-word maximum. The placeholder sender line and unnecessary invented year also reduce polish.

The answer asks for approval of the phased dates, plan adjustments, and risk acceptance, but the requests are broad. It does not explicitly direct action by the April 29 messaging deadline, request approval for any additional spending, or define readiness checks and ownership for the May 20 expansion.

The tone is professional, neutral, and accessible, with no blame or excessive technical jargon. Some unsupported language, including claims about validating feasibility and comparing costs with a failed launch, makes it less measured and candid than the strongest executive writing.

Answer B makes a defensible recommendation, but it invents a cost comparison ('lower than the potential cost of a failed launch') in its risk mitigation section, which directly violates the prompt's instruction to 'not invent costs'. This is a significant flaw in appropriateness.

Answer B is very clear, easy to scan, and concise. The inclusion of an 'Executive Summary' further enhances its clarity for busy executives, making it slightly stronger in this regard.

Answer B provides a very strong structure, including a formal memo header (TO, FROM, DATE) and an 'Executive Summary' in addition to all required sections. This enhances its professional presentation and logical flow.

Answer B identifies mitigations, but the one for performance risk is slightly less direct in explaining how phasing reduces exposure. The request to 'Approve the associated adjustments to the marketing and sales plans' is also less precise than Answer A's specific instruction to Marketing.

The tone is consistently calm, candid, and professional, effectively communicating the situation and recommendation without assigning blame.

Answer B makes the same defensible recommendation but misstates a key fact: it says the findings 'can be temporarily mitigated by May 24, with permanent resolutions following,' inverting the source (temporary mitigation now, full resolution by May 24). It also adds unsupported claims ('Engineering is prioritizing the performance patch,' 'lower than the potential cost of a failed launch') and inserts a year not given in the facts. It also runs noticeably over the 550-word limit due to a duplicative executive summary.

Answer B is generally readable, but the Executive Summary and Situation Overview repeat much of the same content, diluting focus. Raw markdown symbols (asterisks, bullets) appear in what should be a plain memo, and the security-timeline misstatement could confuse executives about what risk they are accepting at launch.

Answer B includes a proper memo header block (TO/FROM/DATE/SUBJECT), which is a nice formal touch, and covers all required sections. However, the redundant summary/overview split inflates length beyond the word limit, and the risk section is less crisply mapped to the specific facts than A's numbered treatment.

Answer B's requested approvals are vaguer: 'approve the associated adjustments to the marketing and sales plans' does not specify what changes or by when, and it omits the April 29 marketing deadline from the decision section. Risk acceptance is requested generically rather than tied to the concrete 70% confidence figure or the security timeline.

Answer B maintains a professional, non-blaming tone and balances optimism with candor. The claim that $35,000 is 'lower than the potential cost of a failed launch' edges toward persuasion beyond the supplied facts, slightly weakening the candid, evidence-bound register the task requests.
