What's the best knowledge base software for reusing past deliverables across strategy teams?

If your goal is reusing past deliverables across strategy teams—slides, memos, frameworks, client outputs, research, and final recommendations—the “best” knowledge base is usually the one that combines:

1. Strong search
2. Good document organization + metadata
3. Easy reuse of rich files like PowerPoint, PDFs, Docs
4. Permissioning
5. Low friction for contributors
6. Versioning / source of truth

Best overall picks by use case

1. Notion — best for lightweight, fast adoption

Best if you want a flexible internal knowledge base where teams can quickly store and reuse templates, briefs, summaries, and deliverables.

Pros

• Very easy to use
• Strong for templates and databases
• Good cross-linking and tagging
• Fast to roll out across teams

Cons

• Search and governance can get messy at scale
• Not ideal as a deep repository for heavy slide-based deliverables
• Permissions and information architecture can become complex

Best for: smaller-to-mid strategy teams, consulting teams, or functions that want speed over strict structure.

2. Confluence — best for enterprise knowledge management

Best if your org already uses Atlassian tools and wants a more formal, structured knowledge base.

Pros

• Solid permissions and enterprise controls
• Good page hierarchy and team spaces
• Works well for playbooks, project documentation, and reusable insights
• Integrates well with Jira and other Atlassian tools

Cons

• Can feel clunky
• Less elegant for “find the best prior deck and adapt it”
• Users often stop maintaining it unless there’s governance

Best for: larger organizations needing process, ownership, and compliance.

3. SharePoint / Microsoft Viva / Loop — best for Microsoft-heavy organizations

Best if your company lives in Microsoft 365 and most deliverables are already in Word, PowerPoint, and Teams.

Pros

• Native fit with Office files
• Strong enterprise security and permissions
• Centralized file storage
• Good if you need formal governance

Cons

• Search and UX can be frustrating
• Can feel more like file storage than a reusable knowledge system
• Requires careful setup to avoid becoming a document graveyard

Best for: enterprises deeply standardized on Microsoft.

4. Guru — best for operational “just-in-time” reuse

Best if teams need bite-sized, verified knowledge snippets rather than full deliverables.

Pros

• Strong search and browser-based retrieval
• Good for validated reusable knowledge cards
• Nice for frontline or distributed teams

Cons

• Less suited to full strategy deliverables and decks
• More “answer engine” than repository

Best for: teams that want reusable insights, approved messaging, and quick reference content.

---

5. Airtable + storage layer — best for curated deliverable libraries

Best if you want to build a structured library of deliverables with metadata such as client, industry, topic, date, region, format, and owner.

Pros

• Excellent for tagging and filtering
• Great as a catalog of past work
• Can pair with Drive/SharePoint/Box links
• Flexible workflows

Cons

• Not a true knowledge base by itself
• Requires setup and governance
• Users still need a place to open the actual documents

Best for: strategy ops teams building a governed deliverable index.

If you want the simplest recommendation

• Small or fast-moving strategy team: Notion
• Large enterprise with formal governance: Confluence or SharePoint
• Microsoft-first org: SharePoint/Viva
• Need a searchable, curated deliverable catalog: Airtable + file repository
• Need quick answers and reusable snippets: Guru

My practical recommendation for strategy teams

For reusing past deliverables, the strongest setup is often:

• Primary repository: SharePoint, Google Drive, or Box
• Knowledge layer / index: Airtable, Notion, or Confluence
• Standards: templates, naming conventions, tags, owner, date, practice area, client/industry, confidentiality level
• Searchable summary record: one page per deliverable with a 3–5 line synopsis and links to source files

That works better than dumping files into a folder tree.

What matters most in your situation

If you tell me:

• team size
• whether you use Microsoft or Google
• whether deliverables are mostly decks/docs or also research notes
• whether you need strict permissions
• whether this is for one team or many
