The simplicity of LEGO instructions
I've been helping build a lot of LEGO sets that my kids got for Christmas.
(Side note, did you know that the plural of LEGO is still LEGO?)
Some of the kits were pretty difficult, but the instructions never were. These instruction books are made for multiple countries and languages, and everyone gets the same book. That's the key, too. For one set, it was a heavy 200 page book, compared to the one sheet of paper from other toys.
It sent me down a Google rabbit hole, and while there is plenty about how LEGO bricks are made, there doesn't seem to be much about the making of the instructions, except this (from Wikipedia):
As of September 2008 the design teams use 3D modelling software to generate CAD drawings from initial design sketches. The designs are then prototyped using an in-house stereolithography machine. These prototypes are presented to the entire project team for comment and testing by parents and children during the "validation" process. Designs may then be altered in accordance with the results from the focus groups. Virtual models of completed Lego products are built concurrently with the writing of the user instructions. Completed CAD models are also used in the wider organisation for marketing and packaging.
I’m possibly oversimplifying it, but it sounds like the key to making good instructions is to:
1) Take your time.
The reference article used in the Wikipedia link says that LEGO uses a 3-step development process: exploring, developing and validating.
Count how many mini-steps there are in that quote paragraph: Initial design, then CAD modeling, prototyping, project team review, validation by children and parents, focus groups, review of the focus groups - that’s at least 7, not to mention the writing and designs of instructions are happening at the same time. This means that there are plenty of opportunities to think out issues.
2) Get feedback from your audience.
That same article mentions that kids are brought in to test the LEGO sets at almost every stage of the design process, and designers go to stores and talk to parents and grandparents buying sets.
That’s it. Take your time and get feedback. Both steps are important, and equally important to each other.
