More effort can stop improving results when the constraint sits elsewhere. An executive adds hours, attends more reviews and checks more detail, while delivery remains slow.
The next step is to identify the work that is limiting progress.
Follow one result backward
Choose an important outcome that has not improved. Trace the decisions, handoffs and resources needed to produce it. Where does work wait? Where is it repeated? Which uncertainty prevents someone from moving?
Ask what the executive's extra involvement changes at that point. It may help resolve a genuine bottleneck, or it may add another approval without addressing the cause.
Try a change with a clear prediction
If the problem is late information, change when and how it arrives. If the problem is conflicting priorities, settle the tradeoff. If the team lacks a capability, decide how to obtain it.
Write down what should become different if the explanation is right. This makes the intervention testable and limits the tendency to defend it after weak results.
Health, fatigue and sustained pressure may also need attention, but they should not be assumed to explain every performance plateau. A careful review leaves room for several causes and directs effort toward the one the evidence supports.
