Scraping the hull: Ridding your organization of barnacles

Editor's Note: A version of this article previously appeared in the March 2004Lean Into It newsletter.

What do barnacles and lean manufacturing have in common? Let me explain.

Barnacles are a form of sea life that everyone's heard of but probably knows little about. Many different types exist, but let's talk about the type of barnacles that attach themselves to ships.

These crustaceans are roughly the size of a quarter, and they attach themselves to a host (ship) for life. The adhesive properties of the cement that they excrete are amazing. This small animal glues itself to a host with a compound so strong that it could hold the weight of a compact car (2,500 pounds).

Estimated costs associated with speed loss (caused by increased drag) and increased fuel consumption resulting from these marine mollusks' growth on ship hulls are an astronomical $1.4 billion per year. "Fouling," as it is referred to, can contribute to an increase in fuel consumption of up to 7 percent after only one month and 44 percent after six months (Swedish International Development Authority, 1986).

For ships, the traditional remedy has been a regular visit to the dry dock. There, barnacles and other organisms are scraped or sandblasted off the hull, which is then covered with a coat of antifouling paint designed to discourage their return. As long as 2,000 years ago, hulls were sheathed with lead and smeared with concoctions of oil laced with sulfur and arsenic. In 1625 a lethal recipe combining arsenic, copper, and gunpowder was considered worthy of an English patent as an antifouling compound.

The danger for shipping companies is that the barnacles are hidden below the water line. Out of sight, out of mind. The only indication that fouling has occurred is the vessel's reduced performance.

Barnacles-Non-value-added Activities Parallel

Could our companies be fouled—slowed down or consuming resources unnecessarily— by barnaclelike behaviors? How do we "scrape the hulls" of our organization to ensure smooth, unrestricted, and cost-efficient advancement?

Barnacles can be likened to the non-value-added activities we perform every day. During a kaizen event at a client company in Nevada, we performed a value-added, non-value added (VA-NVA) observation of a sawing process. The operator was a large man (325-plus pounds). He was working in 95-degree-F heat and wearing a shop coat over his coveralls. This poor man was sweating profusely, to the degree that I was worried about his health. The initial observation showed that he was able to spend only 19 percent of his day in a value-adding mode. Eighty-one percent of his day was spent on either necessary non-value-added tasks (things like paperwork and stacking parts), or, worse yet, unnecessary non-value-added tasks (activities like looking for a supervisor or a pallet).

After the kaizen team rearranged his work area, developed a new work standard, and set his operation up to run at takt time, this worker produced three times as many parts. He now spent well over 60 percent of his time in pure value-added activities (still room for improvement). At the time of our kaizen presentation, he was unaware that he was producing 200 percent more material through his two saws. Before we told him about the documented improvement, we asked him if the new layout and new work steps were easier or harder. He expressed a great deal of satisfaction with the new process, describing it as "so much easier than before." He was producing three times as much, with less effort. Kind of like pushing a ship through water with less effort because the barnacles had been scraped off.

Nondiscriminating Suckers

Organizational barnacles can grow anywhere. Engineering, order entry, purchasing, finance, and, of course, the production departments may need to be put into "dry-dock" and examined for non-value-added activities. A fabrication team VA-NVA examination found that 25 percent of its time was spent in non-value added activities. For this $14M company, this meant $3.5 million worth of potential sales opportunity was being left on the table each year.

Interestingly, after a ship has had barnacles removed, the entire hull must be treated to inhibit barnacle regrowth. So it is with organizations; sustainment is by far the hardest part of improvement. Changing the behaviors of the individuals who comprise the organization is necessary to avoid reverting back to non-value-added activities.

Continuous Improvement

Kaizen must become a way of life, and one trip to the dry dock will not create a barnacle free ocean or organization. Continuous improvementis not just a program title, it is a verb, and verbs demand action. I'm sure that scraping barnacles off a ship isn't easy work, but the rewards of improved performance and reduced costs must be worth it, because every viable shipping company in the world does it.

So, where will you start scraping?

    • Date : 24th February 2020 Events to Look Out For Next Week 24th February 2020.The economic data has been and will continue to be overshadowed by the Covid-19 outbreak. The week ahead starts light, with the German Business Sentiment Index and Chinese Retail Sales on Monday. Leading indicators dominate the releases, but the event of the week is the US GDP and Consumer Confidence, which should shed light on whether the epidemic is visible in the data globally.Monday – 24 February 2020 Japan – Emperor’s Birthday Retail Sales (CNY, GMT N/A) – China’s retail trade growth stood at 8 percent year-on-year in December 2019. However a strong decline is expected for January, following the recent releases indicating that new car sales plunged 92% in China in February and airline traffic is expected to post the first drop since 2011 amid heavy virus containment measures in China. German IFO (EUR, GMT 09:00) – The German Business Sentiment Index released by the CESifo Group is closely watched as an early indicator of current conditions and business expectations in Germany. February’s numbers are expected to incline. Tuesday – 25 February 2020 Leading Economic Index (JPY, GMT 05:00) – The index is expected to show no change in the outlook of the Japanese economy and stand at 91.6. Gross Domestic Product (EUR, GMT 07:00) – German GDP is expected to have fallen by 0.3% on an annualized rate in the last quarter of the year, compared to 1.0% growth in Q3. Conference Board Consumer Confidence (USD, GMT 15:00) – Consumer Confidence is expected to have increased to 132.4 compared to 131.6 in the previous month. Wednesday – 26 February 2020 New Home Sales (USD, GMT 15:00) – The housing recovery should extend into 2020, assuming that mortgage rates remain low and Fed policy remains accommodative. The January new home sales should post a 2.3% climb to a 710k pace, after a dip to a 694k rate in December, versus a 12-year high of 730k in September. Trade Balance (NZD, GMT 21:45) – The Trade Balance measures the difference in value between imported and exported goods and services over the reported period. It will be interesting to see whether the New Zealand trade balance already posts an impact from the epidemic. Thursday – 27 February 2020 Gross Domestic Product (USD, GMT 13:30) – US preliminary GDP growth for Q4 is expected to trim to 2.0% from 2.1%. Durable Goods (USD, GMT 13:30) – Durable goods orders are expected to fall -1.5% in January with a -4.7% drop in transportation orders. Defense orders should fall by -29%, following the 101.4% December surge. Boeing orders declined to zero planes, following a dismal 3 planes in January. Tokyo Core CPI and Unemployment Rate (JPY, GMT 23:30) – Tokyo CPI is usually a good proxy for the Japanese economy’s overall inflation rate. In February, the CPI ex Food is expected to have stood at 0.9% y/y. The unemployment rate is expected to have climbed to 2.3% from 2.2% in December. Retail Sales (JPY, GMT 23:50) – Following a precipitous 3-month dive in October -December, due to a prolonged hit to exports from soft global demand and a slide in consumer spending following a nationwide tax hike, January’s Retail Sales are expected to drop to -1.1% on a y/y basis. Friday – 28 February 2020 Unemployment Rate (EUR, GMT 08:55) – The German unemployment rate is expected to have remained at 5% in February. Harmonized Index of Consumer Prices (EUR, GMT 13:00) – The German HICP inflation could rise to 0.3% m/m for February from the drop seen at -0.6% m/m last month. Gross Domestic Product (CAD, GMT 13:30) – A sharp slowing in Canada’s real GDP growth rate to 1.2% (q/q, saar) is expected in Q4 following the 1.3% Q3 growth. This should not add to the backing for a rate cut for the Bank of Canada. Personal Income (USD, GMT 13:30) – A 0.3% rise in personal income in January is anticipated after a 0.2% increase in December, alongside a 0.2% rise in consumption that follows a 0.3% December gain.
