Building Automated Workflows Step by Step

1

Task Inventory

Track your work for one week and list tasks that could be automated.

Checkpoints

  • • Which tasks take the most time?
  • • What do you do repeatedly?
  • • Where do manual errors frequently occur?
2

Workflow Design

Diagram the workflow to automate, clarifying triggers and actions.

Design Points

  • • Define trigger clearly (what starts the workflow)
  • • Identify data needed at each step
  • • Consider error handling
  • • Set human review checkpoints
3

Tool Selection & Build

Choose the right tools for your workflow and build it.

Selection Criteria

  • • Does it support the apps you need to connect?
  • • Is the free tier sufficient or do you need paid?
  • • Learning curve and build time
  • • Documentation quality
4

Test & Improve

Test your workflow and fix any issues.

Test Items

  • • Happy path: Does it work as expected?
  • • Error handling: Are errors handled properly?
  • • Edge cases: Can it handle unexpected inputs?
  • • Performance: Is execution time acceptable?

Tips for Automation Success

Start Small

Don't jump into complex workflows immediately. Start with simple 2-3 step automations. Build momentum with small wins before expanding.

Keep Humans in the Loop

"Semi-automation" is safer than full automation. Especially for client-facing outputs, include a human review step before sending.

Document Everything

Document how workflows work and their purpose. Helpful for your future self and when you need to outsource.

Review Regularly

Review automated workflows monthly for improvement opportunities. Update as your business evolves.
