Build versus buy
When considering new technology solutions, organizations often face the challenging decision of whether to build custom software, buy an off-the-shelf product, or customize existing systems. Within the AI category, this decision often comes down to whether to select and host an opensource model such as Meta’s Llama, or align with a closed source vendor such as OpenAI or Anthropic. This template helps you create a structured analysis that considers all key factors, resulting in a professional document you can share with stakeholders.

​
When to Use This Template

Use this Build vs Buy Analysis template when:
  • You need to evaluate whether to develop a custom solution or purchase existing technology
  • You’re preparing to present options to senior leadership (like CFOs or CTOs)
  • You need to document and justify your technology procurement approach
  • You want to ensure you’ve considered all major factors in your decision

​
How the Template Works

The Build vs Buy template creates a comprehensive, 1-3 page formal analysis document based on information you provide. Kowalah guides you through a structured conversation about your specific situation, gathering important details about your business objectives, requirements, resources, and constraints. The conversation is broken into manageable stages, with Kowalah asking focused questions in each area to help you think through all relevant aspects of the decision. This guided approach ensures you don’t miss important considerations while keeping the process straightforward.

​
3. Scope and Requirements

​
4. Build Analysis

​
5. Buy Analysis

Assesses potential market solutions, implementation timeline, costs, and specific risks like vendor lock-in or customization limitations.

​
6. Customization Option

Explores whether existing internal systems could be adapted to meet the need, including feasibility, costs, and time requirements.

​
7. Cost and Risk Summary

Provides a side-by-side comparison of all options with a clear summary table highlighting key differences.
