Same vocabulary, different dictionaries.
Most of what looks like disagreement is two people using the same words and quietly meaning different things. You both said done, you both said soon, you shook hands, and you walked away pointed in different directions. Here is how to catch it before it costs you.
Most of what looks like disagreement is not disagreement at all. It is two people using the same words and quietly meaning different things. Same vocabulary, different dictionaries. You both said done, you both said soon, you both said fair, you shook hands, and you walked away confident and pointed in different directions. The argument three weeks later is not about the thing. It is about the definition you never checked.
You can agree on a word and still not agree
An agreement is not a shared word, it is a shared understanding. When those two come apart, the word papers over the gap and both sides feel aligned right up until reality forces the definitions into the open. By then there is work done, money spent, and trust bruised, all because nobody spent the two minutes to ask what the word actually meant to the other person.
Where it bites
Senior
You hire a senior person. You meant runs it without supervision. They meant has done it for a few years. Both true, both different, and you find out on the job.
Handled
You delegate something and hear it is handled. You meant finished and owned. They meant I have started and I am on it. The gap surfaces at the deadline.
Fair
Every partnership dispute is two people who both think they are being fair, using the same word for two different splits. Fair is a feeling until you write down what it means.
Soon
Soon is the most expensive word in business. To one person it is today, to another it is this quarter. Nobody lies, and the project still slips.
The fix
Define the word before you agree on it
When a load-bearing word shows up, stop and define it out loud. Especially the soft ones: done, good, soon, fair, senior, urgent. It feels pedantic and it saves the argument.
Play it back in your own words
Repeat what you think was agreed in different words than they used. If your version and theirs still match, the definitions are shared. If they do not, you just found the gap for free.
Write the definition down
For anything that matters, get the shared definition in writing. This is what a definition of done is for. A written definition cannot drift, and it settles the argument before it starts.
Before your next handshake, hire, or handoff, ask one question: are we using the same word for the same thing. Most of the friction you blame on other people is really just two dictionaries that never got compared.
