Question 1

Why does my schedule keeps falling behind?

Accepted Answer

A schedule typically falls behind when the available capacity does not match the amount of work that has been planned. Common causes include inaccurate time estimates, unexpected tasks, sickness, annual leave, dependencies between activities and a lack of visibility into progress. In most cases, delays are not caused by a single major issue, but by several small deviations that gradually accumulate throughout the process.

Question 2

What is the biggest cause of schedule overruns?

Accepted Answer

Although it varies from one organisation to another, a lack of visibility into capacity is one of the most common causes. Many organisations plan work based on theoretical availability, while employees are often less available in practice due to meetings, annual leave, training sessions and ad-hoc tasks. As a result, a schedule may appear achievable on paper, even though actual capacity is insufficient.

Question 3

How can you tell if a schedule is at risk of falling behind?

Accepted Answer

There are several warning signs that indicate a schedule is under pressure. These include tasks being regularly postponed, growing backlogs, increasing overtime, shifting deadlines and employees consistently working at full capacity. The earlier these signs are recognised, the easier it becomes to take corrective action and keep work on track.

Question 4

How much buffer should you build into a schedule?

Accepted Answer

There is no universal rule that applies to every organisation. The amount of contingency required depends on factors such as the complexity of the work, the predictability of processes and the volume of urgent requests. Many organisations reserve between 10% and 20% of their capacity for unexpected tasks and changes. A schedule that utilises 100% of available capacity often leaves too little room to absorb disruptions.

Question 5

Why does ad-hoc work cause delays?

Accepted Answer

Ad-hoc work disrupts the original schedule because it requires capacity that has already been allocated to other tasks. When employees frequently switch between planned work and urgent requests, the likelihood of deadlines being pushed back increases. This is particularly true when ad-hoc work becomes a regular part of day-to-day operations, leading to growing backlogs over time.

Question 6

What are the consequences of a schedule running behind?

Accepted Answer

A delayed schedule can result in increased workload, more overtime, reduced productivity, higher operational costs and lower delivery reliability. In addition, employees working under time pressure are more likely to make mistakes, leading to rework and further delays. Over the long term, persistent scheduling problems can even contribute to employee turnover and customer dissatisfaction.

Question 7

How can you prevent a schedule from falling behind?

Accepted Answer

Preventing schedule overruns starts with visibility into capacity, progress and potential bottlenecks. By creating realistic time estimates, allowing room for unexpected work, making dependencies visible and continuously monitoring progress, organisations can avoid many common causes of delay. The sooner deviations become visible, the easier it is to make adjustments and maintain control of the schedule.

Question 8

How does planning software help prevent planning problems?

Accepted Answer

Scheduling software provides organisations with real-time visibility into capacity, resource utilisation and progress. This makes bottlenecks easier to identify and enables planners to take action before delays occur. In addition, scheduling software simplifies scenario planning, helps distribute capacity more effectively and ensures that teams are working from the same up-to-date information. This improves decision-making and makes schedules more reliable and predictable.
