Secret of experts: How to recognise HIDDEN LOST OPPORTUNITY?

Years ago I participated in Productivity Audit in a factory of tile stove bricks. The raw materials cost almost nothing (clay, sand, Cornish stone,) bricks formed manually (cheap manual work), only cost were gas for furnace where shaped bricks become final product. Low cost production, people and machines working, demand and prices there – still company on edge of squib! How it is possible?

1. First remarked: out of finished product at the end of the oven, average 62% satisfied quality criteria to be sold at full price.

In average 38% of daily production is loaded, baked, unloaded, transported, controlled, ground again to be added to the raw material.

2. The ratio actually was even worst: 54% was OK, additional 8% obtained after dimension- and crack reparation.

There was a small workshop with operators who transported, repaired, sort 25% of the daily production to be recovered 8% at the end.

3. At brick shaping worked 24 persons. The individual score of workers in shaping vary 52 – 90 per shift.

Variation = 90 -52 =38; (variation/2)*24 =19*24 = 456 So, at daily shaping exit at least 456 bricks (more than 25%) more or less, dependently who came on job.

This is the moment, to zoom in, what a production machine is doing during the shift time (planned production time):

1. A machine is producing at nominal speed
2. A machine is producing (working slower then nominal)
3. A machine is stopped (any reason: no work, failure, waiting time)

We would like to have the case 1 all the time, isn’t it? Sure, but happens cases 2 & 3 as well!

In case 3 is obvious: this is a LOST OPPORTUNITY

Case 2 is tricky. If you look at the machine, it is producing. But if you do not measure hourly outcome and do not compare it to nominal value, you do not know is there a HIDDEN LOST OPPORTUNITY, or not!

Factory described above contains plenty of examples of hidden opportunities, to be recognized:

1. Owen utilization. In average 38 % of the used gas thrown away (wasn’t used to make product)
2. In order to “gain”  more 8% product, 24% of products worked double (time and money thrown away)
3. In lack of skilled persons at shaping lost daily at least 25% of production time. (The same amount could be achieved by 18 skilled workers. Why they paid 24?)  

Conclusion:

In order to be able to recognize: is there a lost opportunity in your company, you need figures and daily evaluation of them. Implementation of relevant KPI’s, proper system of evaluation and fine tuning based on KPI value can dramatically improve productivity situation in a short time! And all we know, that profitability is following productivity!

At the end one question remained: how it is at your organization?
