An integration leader without decision authority can report the same unresolved question every week.
Why it matters when the plan changes
Integration is a dense sequence of decisions that cross both organisations: which system survives, which process wins, who holds a combined role. The work itself, combining the logistical, social and technical systems of two organisations into one, sits across every reporting line rather than inside any single one. Each decision needs settling quickly and each crosses a boundary. A leader who can only escalate turns every one of them into an executive decision, which is slower than either business acting alone.
The tension is that giving real authority to an integration leader displaces the line, which the line resists, and withholding it makes the role a reporting function rather than an accountable one, in the sense that accountability means being individually and ultimately answerable for an outcome. The workable version grants authority over a defined class of decisions for a defined period, with everything else staying in the line and a named executive for the exceptions.
In practice
An integration leader is appointed with a mandate to coordinate and no authority to decide. Eight decisions about which system survives are escalated over three months, each to a different executive, each resolved on its own merits. The resulting architecture is a set of locally sound choices that do not fit together.

What it cannot tell you
The role name does not tell you whether authority accompanies it. Two organisations can both appoint an integration leader and mean entirely different things by it, one a decision-maker, one a coordinator, and the title gives no signal of which. The gap has to be checked in the mandate, not assumed from the job description.
Questions
Decision rights over a defined class of integration questions for a defined period, such as which system survives or which process becomes standard, with everything outside that class staying in the line, and a single named executive to settle the exceptions.
Someone with standing in at least one of the businesses and credibility in the other, who will not be running either afterwards. An external appointment lacks the standing; a future business leader has an interest in the outcome that shapes their decisions.
Until the decisions the combined plan depends on are being made once rather than twice, which is a condition rather than a date. Roles that persist past that become a permanent layer, and the organisation stops learning to coordinate without one.
Every decision becomes an escalation, resolved by different executives at different times on its own merits. The result is a set of locally reasonable choices that do not fit together, which is more expensive than any single wrong decision would have been.
It is the same structural problem in a different context: a function with the best view of the whole and the least authority over any part of it. The same answer applies, which is defined decision rights for a defined period rather than escalation as the operating mode.
