Key insights from Cinareo’s recent conversation with industry experts Mark Alpern and Daniel Piper
This article is the second in a four-part series exploring key themes from Cinareo’s recent conversation with workforce planning experts Mark Alpern and Daniel Piper.
Most workforce plans do not fail because the forecast was wrong. They fail because something changed after the plan was set, and no one saw the impact early enough. By the time results start to drift, the decision has already been made, and teams are left explaining gaps they did not expect.
Mark and Daniel agreed that the real problem usually isn’t the math. In many organizations, planners spend weeks creating precise forecasts, only to see those plans unravel in execution. “Good forecasts don’t fail on paper,” said Daniel Piper. “They fail in practice.”
It usually does not break all at once. A few schedule changes. An exception that gets approved. A shift that goes unfilled. Individually, each decision seems manageable. Together, they start to move the system away from the plan, often without triggering immediate concern.
The Execution Gap
Workforce plans often break in a much simpler way. They are not followed consistently. A model may predict demand accurately, but once daily decisions start to deviate, even slightly, the gap between plan and reality begins to widen.
Daniel pointed to a familiar scenario. “The forecast says you need 150 people, but by midweek you have 130 actually working,” he said. “That difference isn’t a forecast error, it’s an adherence issue.”
The gap between forecast and execution grows quietly. Shift swaps, last-minute time-off approvals, or training changes rarely seem urgent in the moment. But as they accumulate, service levels slip, costs rise, and the original plan becomes harder to recognize. By the time the impact is visible, it is already embedded in the outcome.
Mark added that too many organizations misdiagnose the problem. “When numbers don’t match the plan, everyone blames forecasting. But most of the time, the plan was fine. It just wasn’t followed.”
Workforce Planning as a Team Sport
Fixing this does not start with a better forecast. It starts with alignment. Planning may begin with the forecasting team, but it only holds if operations, HR, training, and leadership are working from the same assumptions and priorities.
“Workforce planning is a team sport,” Mark said. “You can’t plan in isolation and expect consistency.”
He described how silos create friction. HR hires too late for upcoming volume, training teams delay onboarding, or team leads make scheduling decisions without visibility into capacity. Each decision might seem minor, but together they shift reality away from the plan.
Daniel added that even the best planners struggle if other teams are not using the same assumptions or priorities. “If everyone is working from a different version of the truth, the plan doesn’t stand a chance,” he said.
Why Adherence Defines Success
Adherence is often treated as a metric to monitor, but it is closer to a signal of whether the operation is holding together. When adherence starts to slip, it is usually one of the first signs that the plan is no longer reflecting reality.
He noted that consistent adherence creates predictability, the very thing planning is meant to achieve. “Forecasting gives you direction,” Daniel said. “Adherence keeps you on the road.”
Mark agreed, highlighting that adherence data gives planners valuable feedback. “When execution doesn’t match the forecast, the question should be why did something change operationally? Did we under-train, under-staff, or just not follow the plan?”
This feedback loop helps organizations spot where discipline is breaking down and take action before it becomes costly.
Leadership’s Role in Reinforcing the Plan
This is where leadership becomes critical. When managers treat the plan as flexible, teams will do the same. When they reinforce why the plan exists and what it protects, adherence becomes part of how the operation runs, not just something to track.
“Leaders set the tone,” Daniel said. “If they treat the plan as optional, everyone else will too.”
Mark added that when frontline leaders explain how adherence impacts cost, service levels, and customer experience, planners gain credibility and agents understand the bigger picture. This context helps transform the plan from a static document into a shared goal.
It also prevents the common “us versus them” dynamic between operations and planning. When teams see how their actions affect the forecast, collaboration replaces blame.
Visibility Creates Accountability
Visibility was another recurring theme in the conversation. Plans fail when teams cannot see the impact of their deviations in real time.
Mark explained that connecting forecasts, schedules, and live performance dashboards closes that loop. “If planners and operations can both see where things are drifting, they can correct it before it spirals,” he said.
Daniel agreed, adding that visibility should empower, not police. “The goal isn’t to catch people out, it’s to keep everyone working from the same playbook.”
This transparency creates shared accountability. Planners can see when their models hold up; operations can see when they drift. Both gain the insight needed to course-correct together.
Closing the Loop
Forecast accuracy is only the starting point. A well-built plan without adherence, alignment, or visibility does not fail loudly, it drifts. And that drift is what creates the gaps teams are later asked to explain.
As Mark and Daniel emphasized, execution discipline is what turns planning into predictable performance. Workforce planning succeeds when everyone – from forecasters to frontline leaders – sees their role in keeping the plan intact.
Cinareo helps teams bridge that gap by connecting plans to real-time performance. The platform gives leaders and planners the visibility to align, act early, and stay ahead of change.
Getting the forecast right is an achievement. Keeping it right in practice is what drives measurable results.
