What is Idle Time?
Idle time might seem like a harmless pause, but it’s actually a productivity killer that’s not talked about often. Machines sitting idle, employees waiting around, and projects stuck in limbo. That’s idle time in action. But what’s causing it? And why should you care?
In this guide, we’ll break down everything about idle time—what it is, the common causes, and the types you need to know. Plus, we’ll share actionable strategies to minimize idle time and keep your operations running smoothly. Let’s jump right in.
What is Idle Time?
In simple words, the term idle time refers to when employees or machines are ready to work but aren’t being used. It’s like having everything set up for success, yet nothing is actually moving forward. That’s why idle time is also called “waiting time.” It’s when work is on pause, and productivity takes a hit.
To understand this better, let’s imagine you have a Pizza restaurant that’s heading toward a busy night. The oven is hot, and the staff is on standby. However, the complete list of ingredients hasn’t arrived yet. Now, your team is standing idle, waiting, while customers are growing impatient. As a result, you’re losing out on potential orders. That’s idle time in a nutshell.
It’s easy to confuse idle time with downtime, but they’re quite different. Idle time refers to a situation when equipment or workers are capable of doing an activity, yet they’re not able to. On the other hand, downtime means an event in which the whole operation stops due to some unforeseen circumstance like breakdown or failure.
An important first step towards getting the most out of your employees, machinery, and operation is minimizing idle time as much as you can.
Types of Idle Time
Idle time has two main types – planned and unplanned. Let’s unfold each of them:
- Planned Idle Time
Planned idle time, or, in other words, normal idle time, is precisely what it sounds like: an intentional pause within a workflow. It basically occurs when employees or machines are scheduled to take a break or pause activity for some specific reason. Here are a few specific examples:
- Breaks for Employees: Lunch breaks, coffee breaks, or just moments of fresh air outside. The pauses are necessary for the well-being of workers, but this is also the downward period when no work could be happening.
- Machine Maintenance: Machines can’t run forever. The downtime planned to allow for maintenance keeps them in shape to avoid overheating or breakdown.
- Shift Change: In factories or offices with multiple shifts, there’s often a gap when one team clocks out and another clocks in. This transition time contributes to planned idle time.
- Waiting for Parts or Inputs: If production is stopped for new raw materials or replacement parts, the downtime becomes a planned part of the operation.
Planned idle time is a pretty calculated pause. While it might affect productivity in the short term, it often prevents larger, costlier issues from cropping up down the line.
- Unplanned Idle Time
Unplanned idle time is an unexpected problem that strikes suddenly. Unlike other planned breaks, this one is out of the control of management. Here are a few common reasons for it:
- Lack of Raw Materials: Supply chain delays can leave workers or machines waiting around due to the unavailability of raw materials. No materials, no production. It’s as simple as that.
- Micro Stops in Machinery: Sometimes, small faults in machines cause big interruptions. They may seem tiny by nature but development comes to a standstill for a little while, piling up into numerous such stoppages. These micro stops accumulate over time and affect overall productivity-efficiency.
- Dependency Delays: When a team or machine is stuck waiting for another to finish, progress comes to a stop. For example, a printing press might sit idle, waiting for graphic designs from another department.
- Unexpected Breakdowns: Sudden equipment failures bring everything to a standstill until repairs or replacements can be made.
Unplanned idle time is more than just an inconvenience. It terribly affects productivity, wastes resources, reduces output, and risks missed deadlines. While planned idle time is already built into the workflow, consider unplanned idle time as a disruption that requires the quickest possible solution to minimize the blow.
Causes of Idle Time
There can be many causes of idle time, and it mostly depends upon the industry you’re in and the kind of workflow you operate in. However, here are a few common causes that are hard to ignore:
- Administrative Failures
Poor planning or decision-making is a very common cause of idle time. For example, a factory is all set and ready to start but is stopped because someone on the purchasing team forgot to order raw materials. Machines sitting idle, employees on hold, and wasted resources, all because of a small administrative mistake.
To tackle this, you can avoid delays with smarter inventory management strategies.
- Production Line Issues
Snags in production can bring everything to a pause. In manufacturing, this could mean waiting for shipments of raw materials. But that’s not the only reason. Power outages can also result in shut-down operations, or problems can come from work instructions that are unclear and leave employees drumming their fingers on their desks.
- Market Changes
A sudden shift in demand, such as a better product launched by a competitor, can really slow down production. Moreover, economic slumps, recessions, or disturbances like a pandemic can slow the business depending on how seriously supply chains break down. Seasonal interruptions can also have the same effect.
- Poor Onboarding
Another very common cause of idle time is new hires caught in limbo because of training gaps or equipment unavailability. Employees without proper onboarding training can consume a lot of precious time trying to fit themselves into workflows or looking for resources instead of properly utilizing their skills in the right places.
- Unexpected Absences
Illness, family emergencies, or personal challenges may leave teams with a shortage of employees. For smaller teams, the absence of a key team member can create a massive dent in productivity, or, in the worst cases, stop the entire operations for the day.
- Natural Disasters
Industries depending on weather conditions, such as trucking and shipping, are particularly vulnerable to those circumstances. Storms, floods, and other natural disasters can bring operations to a pause while disrupting supply chains. Even through indirect impact, your business may encounter delays in obtaining materials, creating idle time snowballs.
These causes might seem really hard to avoid, but once you identify and address them, it becomes easier to minimize idle time and keep production on the right track.
Strategies to Reduce Idle Time
In an ideal world, operations would operate at 100% efficiency. But let’s face the truth: that does not happen every day. Every facility faces the problem of having to deal with idle time due to a number of factors. However, you can minimize idle time with the right strategies. Here’s how:
- Define Idle Time and Set KPIs
Start by clearly defining what idle time means for your operations. Is it unplanned downtime? Waiting for materials? Or delays in production handoffs? Once you’ve defined it, set Key Performance Indicators (KPIs) to measure and track it. This gives you a baseline to understand idle time and improve from there.
- Use CMMS Software
Keeping track of idle time manually sounds like a day with your paperwork. Instead, tackle this issue by using CMMS software. For example, platforms like LLumin can record idle time, analyze trends, and identify root causes. These insights help you tackle issues before they escalate.
- Provide Clear Instructions for Team Members
Unclear work orders can lead to confusion, delays, and wasted time. Make sure your team has:
- Detailed step-by-step procedures for each job.
- Up-to-date information on inventory, equipment, and schedules.
Less ambiguity and more communication = smooth workflow with no guesswork involved. Also, you can streamline tasks and reduce idle time with work order management.
- Optimize Asset Maintenance
One of the most common reasons for idle time is equipment failures or inefficiencies. You can fix this by:
- Centralizing asset data for streamlined preventive and corrective maintenance.
- Automating workflows for work order execution and maintenance tasks.
Keeping every piece of machinery in great condition will minimize unplanned idle times and make sure your operations run as they’re intended to.
How to Calculate Idle Time
The good news is that you don’t need to be the most genius person in the room to calculate idle time. In fact, it becomes super simple when you use the Idle Time Formula, which is:
Idle Time = Scheduled Production Time – Actual Production Time |
- Scheduled Production Time: The amount of time equipment is planned to operate, as determined by management. This can be calculated daily, weekly, monthly, or even yearly.
- Actual Production Time: The actual amount of time the equipment is operational and performing its tasks as intended.
Let’s break it down with an example. Let’s say there’s a printing company that operates a high-speed printer scheduled to run for 12 hours a day. Within this timeframe:
- The printer takes breaks between jobs for paper reloads and setting adjustments.
- There are 30 minutes of planned downtime for routine maintenance checks.
- There’s also a 15-minute lunch break.
On a given day, the printer runs smoothly for 10 hours and 15 minutes, but a technician’s delay in reloading paper adds an extra 10 minutes of unplanned idle time. The actual production time for the day becomes 10 hours and 5 minutes.
By subtracting the actual production time from the scheduled production time, the total idle time is 1 hour and 55 minutes (including planned downtime and breaks). That unplanned 10-minute delay eats into efficiency and impacts overall productivity.
If all this sounds confusing, you don’t have to do the calculations yourself. Instead, as mentioned before, you can use Computerized Maintenance Management System (CMMS) software to run the numbers. A CMMS solution does the idle time tracking/reporting for you by:
- Logging scheduled production time and actual operational hours.
- Tracking planned maintenance in advance and recording unplanned breakdowns in real-time.
- Highlighting the causes of delays, like waiting for parts or technician availability.
It also categorizes idle time and generates detailed reports, helping teams identify patterns and root causes. Integrated systems can then analyze trends to offer actionable insights, enabling management to reduce idle time and improve productivity.
