Process Improvement: Finding and Fixing Bottlenecks

Every Business Has Bottlenecks -- Most Owners Just Cannot See Them

You know the feeling. Work piles up at one point in your process while everything else waits. Estimates take too long. Materials show up late. Invoices do not go out for weeks after a job is done. These are bottlenecks, and they are silently eating your profit margin.

Process improvement is not some corporate buzzword reserved for Fortune 500 companies. It is the practice of looking at how work actually flows through your business and making it flow better. The American Society for Quality defines continuous improvement as an ongoing effort to improve products, services, or processes -- and it applies to a five-person plumbing company just as much as it does to Toyota.

How to Find Your Bottlenecks

Before you can fix anything, you need to see the problem clearly. Here are proven methods:

Map the Process

Pick one core process -- say, from "customer calls" to "job completed and paid." Write down every single step. Every handoff. Every waiting period. Most owners are shocked at how many steps are actually involved.

Draw it on a whiteboard or use sticky notes on a wall. Include:

• Who does each step
• How long each step takes
• Where work sits waiting between steps
• Where errors or rework typically happen

Measure the Time

Track cycle time (how long the whole process takes) versus process time (how long someone is actually working on it). The gap between those two numbers is your waste. If a job takes 10 days from estimate to completion but only involves 20 hours of actual labor, you have 8+ days of waiting, delays, and inefficiency to examine.

Ask Your People

Your employees know exactly where the problems are. They deal with them every day. Ask direct questions:

• "What part of your job wastes the most time?"
• "Where do things get stuck waiting for someone else?"
• "What task do you have to redo most often?"

The Five Most Common Bottlenecks in Small Business

1. The owner is the bottleneck. Every decision, every approval, every customer question routes through one person. This is the most common and most damaging bottleneck in small businesses.

2. Estimating and quoting. Leads come in but estimates go out slowly, and by the time you follow up the customer has hired someone else.

3. Invoicing and collections. The work gets done but the money does not come in for 30, 60, or 90 days because nobody is staying on top of billing.

4. Material procurement. Jobs stall because materials were not ordered in time or the wrong materials showed up.

5. Communication gaps. Field crews do not know about change orders. Office staff do not know job status. Customers do not get updates.

Fix the Constraint, Not the Symptom

When you find a bottleneck, resist the urge to just throw labor at it. Ask why five times. The ASQ's root cause analysis framework pushes you to dig past the surface:

• "Why are estimates taking so long?" Because I am the only one who does them.
• "Why are you the only one?" Because nobody else knows our pricing.
• "Why does nobody else know the pricing?" Because it is all in my head.
• "Why is it all in your head?" Because I never documented it.

Now you have a real fix: document your pricing methodology and train someone else to estimate.

The PDCA Cycle for Small Business

Plan-Do-Check-Act is the foundation of process improvement, endorsed by both NIST and ASQ:

1. Plan: Identify the problem, gather data, propose a solution
2. Do: Implement the change on a small scale -- one crew, one week, one job type
3. Check: Measure the results. Did cycle time decrease? Did errors go down? Did revenue per job improve?
4. Act: If it worked, standardize it across the business. If not, adjust and try again.

Do not overhaul everything at once. Pick one bottleneck, run one improvement cycle, measure the result, then move to the next one.

Quick Wins That Work

• Batch similar tasks. Do all estimating on Tuesday and Thursday mornings instead of reacting throughout the week.
• Create templates. Standard estimate templates, email templates, and checklists eliminate reinventing the wheel on every job.
• Set WIP limits. Cap the number of active jobs so nothing sits half-finished for weeks.
• Automate reminders. Use your CRM or project management tool to trigger follow-up reminders for estimates, invoices, and callbacks.
• Move approvals downstream. Empower foremen and office managers to approve routine decisions up to a dollar threshold without your involvement.

Measuring Improvement

You cannot improve what you do not measure. Track these numbers before and after any process change:

• Cycle time: Total time from start to finish
• First-pass yield: Percentage of work done right the first time
• Throughput: Number of jobs or tasks completed per period
• Cost per unit: Total cost divided by output
• Customer satisfaction: Complaints, reviews, repeat business rates

Even rough measurements are better than none. The goal is direction, not decimal-point precision.
