Why Engineering Documentation Matters
Learn why FTC teams document their work, how a daily engineering log differs from an engineering portfolio, and what a portfolio usually contains.
In this lesson you will
- Explain why engineering documentation helps both the team and the judges.
- Compare a daily engineering log with an engineering portfolio.
- Write a complete daily log entry using a consistent template.
- Identify the sections a typical engineering portfolio contains.
Lesson
Every team builds a robot, but judges cannot see the weeks of thinking, testing and fixing that went into it just by looking at it. Engineering documentation is how you make that work visible. It is also how your own team remembers what you tried, what failed and why you made each choice.
Why document at all?
- Memory: in six weeks nobody will remember why the arm is 30 cm long. A log entry will.
- Teamwork: a member who missed a meeting can read the log and catch up without slowing everyone down.
- Better engineering: writing down a goal and a result forces you to measure instead of guess.
- Judging: judges use your documentation to understand your process, not only your final robot.
- Next season: new members can learn from your mistakes instead of repeating them.
Two different documents
Beginner teams often mix up two things. The daily engineering log is the raw, complete record you write at every meeting. The engineering portfolio is a shorter, edited document built from that log to show judges your best evidence. You cannot write a good portfolio without a good log behind it.
| Daily engineering log | Engineering portfolio | |
|---|---|---|
| When | Written during or right after every meeting | Assembled and updated before competitions |
| Audience | Your own team | Judges and other readers outside the team |
| Content | Everything: ideas, failures, measurements, tasks | Selected highlights that tell your technical story |
| Length | Grows all season | Limited, often to a set number of pages (check the current manual) |
| Style | Quick, honest notes and sketches | Clear layout, captions, summaries |
- 1HeaderWrite the date, who attended and who is writing the entry.
- 2GoalState what the team planned to achieve in this meeting in one or two sentences.
- 3Work doneDescribe what each sub-team did, with sketches, photos or measurements.
- 4ResultsRecord what worked, what did not, and any numbers you measured.
- 5Next stepsList the tasks for the next meeting and who owns each one.
What a portfolio usually contains
- Team overview: who you are, your roles and your goals for the season.
- Engineering process: how you plan, design, prototype and test.
- Robot subsystems: drivetrain, mechanisms and how they evolved.
- Programming: Autonomous and Driver-Controlled (TeleOp) approach, sensors and key code ideas.
- Testing and results: data that shows how you measured and improved the robot.
- Team and outreach: how you work together and share STEM with others, if relevant to your goals.
- Next steps: what you plan to improve and why.
Paper or digital logs both work. What matters is that entries are dated, never secretly rewritten later, and stored where the whole team can find them. If you correct a mistake, add a note with the new date instead of deleting the old text.
Key terms
- Engineering documentation
- Any written, drawn or photographed record of how a team designed, built, tested and improved its robot.
- Daily engineering log
- A dated, complete record of every meeting that lists goals, work done, results and next steps.
- Engineering portfolio
- A shorter, edited document built from the log that shows judges the team's process and best evidence.
- Competition Manual
- The official FIRST document for the current season that defines rules, judging, awards and portfolio requirements.
Practical exercise
Set up your team's documentation system
- 1Create a shared folder with subfolders for the log, photos, CAD screenshots, test data and the portfolio.
- 2Write a daily log template with the five parts: header, goal, work done, results and next steps.
- 3Fill in a log entry for today's meeting using the template.
- 4Make a rotation list showing who owns the log entry at each meeting for the next four weeks.
- 5Find the current Competition Manual and note the section that describes the portfolio requirements.
