Ainda acerca da Produtividade

"Redefining Manufacturing Productivity"
.
"If the traditional definition of productivity is output per worker hour, most improvement efforts historically have been focused on the denominator in that equation: worker hours."
...
""Over the past 20 years, manufacturing plants were considered outside the domain of the business itself," says Peter Martin, vice president of strategic ventures at Invensys Process Systems. "Executives viewed plants as necessary evils, and they focused a lot of their productivity improvement activities on headcount reduction."
.
In the 1970s and 1980s, the investments in new plant floor automation and control systems were most often justified by headcount reductions. Productivity-focused technology investments were calculated primarily to reduce labor costs rather than streamline or reengineer core processes.
.
As a result, Martin says, "In the '70s and '80s, we saw huge reductions in the headcount of field and control room operators. In the '80s and '90s, the focus was on automating maintenance, and headcounts in maintenance departments plunged. And, in the '90s and 2000s," he says, "the focus has been on engineering.
.
It's gotten to the point that many plants found themselves below the critical mass level in terms of headcount.
.
So the focus on reducing headcount as a way to generate productivity is over."
.
Now, Martin says, manufacturers must shift their focus from the headcount denominator part of the productivity equation to the numerator: making sure the plant is operating at maximum efficiency, that assets are generating the greatest possible return on investment, and that companies are agile enough to recognize shifts in demand and to respond to them quickly.
In order to do that, experts say, manufacturers must leave behind the notion that the plant is a necessary evil, divorced from the rest of the business. Plant-level processes and systems must be integrated with the processes and systems of the extended enterprise such as sales, fulfillment, and procurement, so that business managers and manufacturing operators alike have better, up-to-date visibility into not just how well a machine or production line is operating in isolation, but how well it is contributing overall to profitability, return on assets, and production goals.
.
With that kind of integrated view, analysts say, the definition of productivity itself will change. Rather than finetuning operations so that they simply pump out the most widgets per hour, manufacturers will be able to optimize, for example, on profitability or the ability to respond quickly to changes in demand."
