Why it is not presentable

  • Did not give the analysis's recommendation within the first two slides
  • A slide the judges rated as needing work
  1. Slide 1 of Mistral Large 4's deck
    Slide 1Polished Plain text-only cover; the proposed £2.4m budget is not visually emphasised.
  2. Slide 2 of Mistral Large 4's deck
    Slide 2Acceptable The topic title and four equally weighted takeaways do not establish one main conclusion.Title is a topic label ('What We Learned') rather than a takeaway
  3. Slide 3 of Mistral Large 4's deck
    Slide 3Polished Yellow bars break the deck's green chart colour convention
  4. Slide 4 of Mistral Large 4's deck
    Slide 4Acceptable The left side relies on a fairly dense bullet list rather than highlighting the test budget and measurement approach.£150 bar exceeds the top y-axis tick (£140), and its label crowds the chart title
  5. Slide 5 of Mistral Large 4's deck
    Slide 5Acceptable All table rows have equal visual weight; the total and largest budget changes are not highlighted.Title is a topic label; the takeaway sits in the subtitle
  6. Slide 6 of Mistral Large 4's deck
    Slide 6Acceptable The question title and generic subtitle do not state a specific takeaway.Text-only slide that largely repeats points from slides 2–4
  7. Slide 7 of Mistral Large 4's deck
    Slide 7Needs work Using both bullets and numbers creates redundant list markers.Bullet markers and manual numbers both appear ('• 1.'), a formatting defect
