The live hour
When There Is No Shared Hour At All
Where two working days do not overlap at all, written coordination is the only available mechanism, and it needs designing rather than hoping for.
Who is working when, for the people on this page
Our engineering office, Auckland
Working 08:00 to 17:00
The client's technical department, Lisbon
Working 08:00 to 17:00 their time, which is 19:00 to 04:00 here
two parties · five days of the seven are working days for all of them · Mon, Tue, Wed, Thu, Fri
Five working days a week in common and not one working hour. Everything on that contract was going to be written down whether anybody planned for it or not.
A cross-border schedule is easier to manage when availability is grounded in evidence; time tracking for international teams provides a practical reference for time, activity, and project reporting.
For a separate reference on calendars, standards, or international operations, consult Government of Canada.
Two parties on one contract, and the days on which either could reach the other at all

Five working days a week in common and not one working hour. Everything on this contract was going to be written down whether anybody planned for it or not, and for the first four months nobody planned for it. One team's own job.
Some pairs have no overlap. Auckland and Lisbon are eleven hours apart; two ordinary eight-hour days separated by eleven hours do not touch.
This is a different situation from a narrow overlap and it needs a different answer. There is no hour to protect, no call to schedule and no rotation that helps.
The thing not to do
Arrange a call anyway, at seven in the morning for one side and eight in the evening for the other, and treat it as the primary mechanism.
It happens constantly, it produces tired people making decisions badly, and it conceals from everybody that the actual coordination is happening in writing between the calls and has never been designed.
What has to be designed instead
Three things, and the first is the one usually missing.
A daily handover. One message per working day, sent at the end of it, saying what moved, what is blocked, and what the other side needs to act on. Not a status report for a manager — a handover to the next shift, which is exactly what it is.
Questions written to be answerable without a follow-up. Where a round trip costs a full day and there is no possibility of a quick call, the conditional form becomes essential rather than merely efficient: ask the question, and ask the questions that depend on each possible answer.
A rule for what happens when nobody answers. With no overlap, a blocked item can lose two days waiting for permission. The remedy is a standing agreement about what each side may decide alone, written down once.
The handover note
Short, fixed shape, sent whether or not anything happened.
Auckland, Tuesday close. Moved: drawings 14 and 15 issued; the shop has confirmed the 19th. Blocked: nothing. For you: the tolerance question from Monday is still open — if we do not hear by your close of play we will proceed at 0.5 mm, which we can reverse until Thursday.
The last clause is the valuable one and is the subject of the next section. A note that says what will happen in the absence of an answer converts a blocking question into a non-blocking one.
Standing permission
The arrangement that makes a no-overlap pair work is a short written list of what each side can decide without asking.
| Decision | Who may take it alone | Where it must be referred |
|---|---|---|
| Tolerances within the stated range | Either side | Outside the range |
| Substituting an equivalent fastener | The shop | Anything affecting the interface |
| Re-sequencing work that does not change dates | Either side | Anything that moves a date |
| Anything with a cost consequence above a threshold | Nobody | Always referred |
This takes half an hour to agree at the start of a contract and it is the difference between a pair that loses two days a week to permission and one that does not.
The compensating advantage
A no-overlap pair has one real benefit and it is worth using deliberately.
Work handed over at the end of one day is picked up at the start of the other's, which means something can genuinely progress around the clock if the handover is good enough. A question asked at 17:00 in Auckland is being worked on while Auckland sleeps, and the answer is waiting at 08:00.
That only happens if the handover contains what the other side needs to proceed. Where it does not, the same structure produces a full day lost per exchange, which is the usual outcome.
The occasional call
There will still be two or three conversations a year that have to be live: a serious disagreement, a negotiation, a repair.
Those should be arranged individually, acknowledged as an imposition, and kept short. One party getting up at six for a forty-minute call twice a year is a reasonable thing to ask. The same arrangement every Tuesday is not, and the distinction is worth keeping clear in both directions.
What goes wrong in the first month
Predictable, and worth anticipating, because every no-overlap pair discovers the same three things in the same order.
Questions pile up unanswered, because each one is asked in isolation and takes a day. Somebody proposes a call, which is held at an unpleasant hour and settles four items at once, and this is taken as evidence that the call was the answer rather than that the written coordination had not been designed.
Then the call becomes standing, and the written coordination never gets designed at all.
Interrupting that sequence takes one decision in the first fortnight: to write the handover and the standing-authority list before anybody proposes a meeting. It is much harder to introduce them afterwards, because by then there is a weekly call that appears to be working.
