It's the Paper, Stupid --Dickeson

October 2003

Keeping Time

Follow the paper into WIP—work in process. Note the date and time the paper enters production. Next, note the date and time it leaves production and becomes part of a receivable. Subtract exit time from entry time and we know the WIP dwell-time. The greater the WIP dwell-time, the less the profit. (We're not making a nickel while the paper is in WIP.)

Want the granular detail for the WIP? Then track the time of make-readies, stops, delays, production and queue-time between production stages. Is it important to know this detail? Depends on your desire for continuing process improvement and how much profit you want to make.

Forget all notions of holidays or weekends, or chargeable or non-chargeable time. Time is time, an hour is an hour, regardless of what you call it.

Paper won't leave WIP until the job is invoiced. The greater the invoice-time, the less the profit. (We're not making a nickel until it's billed.)

Follow the paper into accounts receivable. As long as it's in a receivable you still haven't captured that elusive nickel. Note the date and time the job becomes part of a receivable. Next, note the date and time payment is received. The difference between billing and collecting is the receivable dwell-time.

We've been following the paper. We've tracked it from raw material through receivable collection. Now we have a paper-time profile for a job, based on the paper-track. The smaller that time profile, the greater the profits of the printing business will be. Is it important to know the time profile? Only if you're interested in making money!

Naming the Enemies

Want to know a secret? We've been applying the logic of Goldratt's Theory of Constraints (TOC). Anything that constrains the velocity, the speed of movement of paper in our commercial printing business is our enemy. We're following the footsteps of Toyota, Dell, Wal-Mart and all of the other businesses that have learned the TOC lesson. Attack the most important constraint first. Minimize or eliminate it. Then move on to the next most important constraint and attack. Never stop. Just keep going! Continuously improve!

Paper waste and turnover velocity are the keys to unlock the success of a printing enterprise. Please note that we haven't said a single word about Budgeted Hourly Costs. They're a charming irrelevance—a nuisance and a distraction. (You can't make that nickel studying hourly costs.)

No matter how you slice it, it's all about the paper, isn't it? When you forget the basics of our business and get all knotted up in job costs, you take your eyes off the prize.

We have to measure the two aspects of paper usage: waste and dwell-time. For each we must look at the global profile and the local, or granular, detail in order to manage the business. It doesn't take rocket science. It just takes common sense, patience and a clear head. Why do we insist on making it so damned difficult?

It's the paper, stupid! Follow the paper.
