Line Manager or Project Lead
In matrix organisations two people have a claim on the approval and each knows half of what is needed. Most implementations pick one and lose the other half.
Matrix team, four projects
No review possible
Submitted
Approved by line manager
Approved
Project splits unchecked
Time taken
4 projects, 1 approver
Line manager, no project involvement · The allocation is the part that mattered.
Where people work on projects but report to a function, two different people have a legitimate interest in the timesheet and neither can review all of it.
The approval issue in “Line Manager or Project Lead” becomes easier to diagnose when the record shows both the submitted hours and the operational context around them. A team evaluating time tracking software with accountable controls for time tracking software should define what an approver must actually check, how a disputed entry is returned and which activity signals are context rather than proof that the work occurred.
The line manager knows the person: whether they were working, whether they were ill, whether the total is plausible, whether something is going on. The project lead knows the work: whether those eleven hours on that work package are credible, whether the split between two projects reflects what happened, whether the narrative matches the task.
For a separate benchmark relevant to “Line Manager or Project Lead”, consult the Harvard Business Review management resources. Use it to test record quality, approvals, retention, employee rights and exception handling against the real workflow rather than treating a software report as self-explanatory evidence.
What each one can and cannot see
A line manager approving a week split across four projects can assess the total and nothing else. The split — which is the part that drives billing, claims and project cost — is invisible to them, and it is the part most likely to be wrong.
A project lead approving their slice can assess that slice precisely and has no view of the person's whole week. They cannot tell that the person has also claimed thirty hours to two other projects, taking the week to seventy.
Pick either one alone and you lose the other's half. Most implementations pick the line manager, because that relationship is in the HR feed, which means the organisation systematically does not review the dimension that costs it money.
The two-stage arrangement
The common solution: project leads approve their own allocations, then the line manager approves the assembled week.
It works and it has two costs. It doubles the number of approval actions, which matters when the arithmetic of attention is already tight. And it introduces a sequencing problem — the line manager cannot approve until every project lead has, so one slow project lead holds up the whole week and, through it, the payroll deadline.
The sequencing problem is manageable if the line-manager stage is a check on the total rather than a full review, and if unapproved project slices escalate rather than block.
The lighter alternative
Project leads do not approve; they receive a notification of hours booked to their project and can raise a query within a window. The line manager approves the week as normal.
This is weaker — silence is consent — and it is far cheaper, and for organisations where the project dimension is used for internal reporting rather than for billing or claims it is usually proportionate. Where the hours are billed or claimed, it is not enough, because the standard applied downstream assumes somebody affirmed the allocation.
Deciding which you need
The question is what the allocation dimension is used for. If project splits feed only internal management reporting, line approval plus notification is adequate. If they feed client invoices, grant claims or capitalisation, somebody with project knowledge has to affirm them, and the organisation should expect to pay for that in approval actions.
Write the answer down, because it is the justification for the extra stage and the thing that will be questioned the first time the deadline is missed.
Shared resources and the honest total
A further failure specific to matrix work: nobody owns the question of whether the week adds up. A person on four projects can plausibly over-claim across all of them while every individual slice looks reasonable.
The check is trivial — total hours per person per week against contracted plus authorised overtime — and it belongs at the line-manager stage, which is the only point where the whole week is visible. Where that stage has been removed in favour of project-only approval, nothing performs it, and the organisation has a population whose weeks nobody ever totals.
Telling the project lead the person has moved
A recurring failure specific to matrix work: somebody comes off a project and nothing tells the project lead to stop expecting their hours, or tells the person to stop booking to the code. Entries continue for weeks against a project they have left.
The assignment record usually knows. Closing a person's access to a project code when their assignment ends, and notifying both the person and the lead, removes the most common source of misallocation in project organisations. It is a small piece of plumbing between two systems that in most places have never been connected.
