The Best Consulting Section Header Slides: How MBB Firms Divide a Deck
A section header slide signals a major structural transition — it's the visual equivalent of a chapter break. In MBB decks, these slides do more than create navigation. They set up the argument of the section before a single data slide appears.
Two types of section headers in consulting decks
Type 1: The repeated agenda (header horizontal). The deck's agenda slide is reproduced, with the current section highlighted. This is the most common McKinsey approach — it re-grounds the reader in the overall structure at each transition.
Type 2: The standalone section title (header vertical). A single slide with the section number, title, and sometimes a one-paragraph framing statement. This is more common in BCG and Bain. It's more dramatic — it feels like the opening of a chapter — but requires the reader to hold the overall structure in memory.
McKinsey uses Type 1 almost exclusively. BCG uses both. Bain leans toward Type 2 in client deliverables and Type 1 in published reports.
The section header as a mini-thesis
The best section headers in MBB decks don't just name the section — they state the section's finding in one sentence. This is the action title principle applied to the section level.
Weak vs. strong section headers
✗ Weak — describes the topic
"Section 2: Market Analysis"
✓ Strong — states the finding
"Section 2: The addressable market is three times larger than current estimates — and concentrated in two underserved segments"
✗ Weak — describes the topic
"Section 3: Strategic Options"
✓ Strong — states the recommendation
"Section 3: Of the four options evaluated, one creates substantially more value with lower execution risk"
Visual treatment across firms
McKinsey header slides are typically spare — the agenda reproduced in clean typography, with the active item in a stronger weight or color. Minimal visual decoration. The sophistication is in the language, not the design.
BCG header slides use more visual weight — a large section number, bold typographic hierarchy, sometimes a dark background section. BCG's section titles feel like book chapters: deliberate, weighty, positioned to be remembered.
Bain header slides often include a brief "section context" block — two or three sentences beneath the title that explain why this section matters in the context of the overall argument. This is particularly useful for multi-audience decks where some readers may skip directly to a section.
The "pillar" variant: BCG and McKinsey
Both BCG and McKinsey use "pillar" slides — a type of section header that displays three to five parallel elements side by side, with each pillar representing a strategic initiative, a key finding, or a component of a framework.
The pillar slide is particularly effective at the start of a recommendations section: "We recommend a three-part response" — and then three visual pillars, each with a name and brief description. The parallel visual structure signals that the three things are equally important and mutually reinforcing.
Pillar slide structure
01
Strengthen the core
Improve margins in existing markets through pricing and mix optimization
02
Expand adjacencies
Enter two high-growth segments where current capabilities transfer directly
03
Build new capabilities
Invest in digital and data infrastructure to enable the next phase of growth
When to use section headers and when to skip them
Section headers make sense when: the deck has 20+ slides, covers distinct topics that require a mental reset, or will be navigated non-linearly (e.g., a board member jumping to the recommendations).
Skip section headers when: the deck is under 15 slides, the sections flow continuously without sharp topic breaks, or you're working in a fast-paced meeting context where pauses for navigation slow momentum.
