Title: [Provide a short, descriptive title for this decision. Example: "Adoption of Go Programming Language"]

Status: Proposed Accepted Implemented Superseded Deprecated


# Context

# What is the background to this decision?

What is the problem you're trying to solve? Why is this decision needed?

  • Summarize key challenges or drivers prompting this decision (e.g., technical issues, complexity, scalability problems, team motivation, or new requirements).
  • Include relevant organizational or project context.

Example: “Our team has been facing challenges in maintaining a monolithic codebase, which has become difficult to scale as the organization grows. To improve scalability and deployment velocity, we are evaluating the adoption of a microservices architecture.”


# Decision

# What decision have you made?

Explain the specific decision being made here. Write it as a clear, single action statement.

  • Example 1: "We will adopt the Go programming language for CLI applications."
  • Example 2: "We will transition from a monolithic architecture to a microservices-based architecture."
  • Example 3: "We will implement Kafka as our event streaming platform for asynchronous communication."

# Rationale

# Why did you choose this decision?

Explain why this option was selected. Provide sound reasoning:

  1. List the factors that influenced the decision (e.g., scalability, performance, simplicity, or team fit).
  2. Mention evidence or research supporting the decision:
    • Compare results from evaluations, Proof of Concepts (POCs), or benchmarks.
    • Mention outcomes of discussions with stakeholders where applicable.
  3. Highlight relevant strengths of the chosen solution.

Example:

  • Simplicity and readability: Go's simple syntax helps reduce complexity for developers, promoting better productivity.
  • High-performance: Go is compiled into optimized machine code, offering faster execution compared to interpreted languages.

# Implications

# What are the implications of this decision?

Outline the consequences of making this decision. Include any potential benefits, costs, risks, or required changes impacting the team, tooling, or processes. Break it into sub-sections:

  1. People/Training: What skills will team members need? Will training or onboarding be necessary?
  2. Process Adjustments: Are there changes needed to workflows (e.g., CI/CD pipelines, coding standards)?
  3. Tooling: Are there tools that need to be adopted or replaced for this decision to succeed?
  4. Risks: List any potential risks with explanations (e.g., lack of experience with the new technology).

Example:

  • Training: Developers will need training to effectively use Go.
  • Dependencies: Existing Python-based tools and libraries must be re-evaluated or migrated.
  • Risks: Temporary decrease in development velocity due to learning curves.

# Trade-Offs

# What are the pros and cons of this decision?

  • Benefits: Clearly state the advantages offered by this decision.
    • Example: Improved scalability, reduced complexity, faster onboarding of new developers.
  • Drawbacks: Acknowledge known downsides or negative consequences of this decision.
    • Example: Increased operational complexity, difficulty managing multiple microservices.

# Key Evaluation Metrics

# How will success be measured?

Define clear criteria to measure whether the decision solves the intended problems.

  • Example metrics might include:
    • Reduced Mean Time to Recovery (MTTR)
    • Faster deployment time
    • Improved system performance (e.g., 20% faster request handling)
    • Improved developer productivity or reduced onboarding time

# Conclusion

# What is the final recommendation?

Summarize the rationale and expected outcome of adopting this decision. Keep it concise. State why the benefits outweigh the challenges, and provide a high-level overview of the next steps or actionable milestones.

Example:
"We recommend adopting the Go programming language due to its simplicity, performance, and strong ecosystem support. While there will be an initial training period and tool adjustments, we believe this change will improve developer productivity and simplify our software architecture in the long term."
