Following up on Roland’s January 4 post,
for an interesting discussion of the use of checklists in the construction
industry readers should pick up The Checklist Manifesto: How to Get
Things Right, by Atul Gawande (the author of the article referred to in
Roland’s post). In a chapter entitled The End of the Master Builder,
Gawande points to the construction industry as a validating example of
checklist success.
Gawande, a doctor, was prompted to investigate the construction
industry further when observing the construction of a skyscraper and reflecting
on how the workers could be sure they were properly constructing such a complex
building. Gawande asks the following questions, “First, how could [the
workers] be sure that they had the right knowledge in hand? Second, how could
they be sure that they were applying this knowledge correctly?” As Gawande
describes it, the problem of construction complexity is daunting.
In designing a building, experts must take into account a
disconcertingly vast range of factors: The makeup of local soil, the
desired height of the individual structure, the strength of the materials
available, and the geometry, to name just a few. Then, to turn the paper
plans into reality, they presumably face equally byzantine difficulties making
sure that all the different tradesmen and machinery do their job the right way,
in the right sequence, while also maintaining the flexibility to adjust for
unexpected difficulties and changes.
Yet builders clearly succeed.
With these questions in mind, Gawande set out to learn how
architects, engineers, and contractors construct complex buildings. He
talks with engineers, project managers, and other personnel involved in the
construction of a medical center near his office in Boston. In the course
of his research, he learns that historically building were built by a “Master
Builder,” a single individual who was responsible to design, engineer, and then
oversee all the details of construction. The “Master Builder” concept
largely relied on the judgment and expertise of that one person. But
according to Gawande, by the middle of the 20th century “[t]he
variety and sophistication of advancements in every stage of the construction
process had overwhelmed the abilities of any individual to master them.”
In Gawande’s telling, what emerged to replace the “Master
Builder” model was increased specialization combined with the use of modern
construction and submittal schedules, essentially checklists that ensure that
the dispersed knowledge of all the different construction specialists gets
considered and incorporated into the project. Gawande states, “What
results is remarkable: a succession of day-by-day checks that guide how
the building is constructed and ensure that the knowledge of hundreds, perhaps
thousands, is put to use in the right place at the right time in the right
way.” Gawande focuses in particular on how the construction and submittal
schedules are flexible enough to deal with even the most complex construction
problems. Many problems are not amenable to a simple checklist
solution. Construction projects often involve complex engineering
questions that require individual judgment under uncertain conditions. In
these uncertain situations, Gawande points out that the schedules didn’t
dictate specific construction tasks, instead they specified “communication
tasks.”
According to Gawande:
For the way the project managers dealt with the unexpected and
the uncertain was by making sure the experts spoke to one another – on X date
regarding Y process. The experts could make their individual judgments,
but they had to do so as part of a team that took one another’s concerns into
account, discussed unplanned developments, and agreed on the way
forward….
In the face of the unknown – the always nagging uncertainty
about whether, under complex circumstances, things will really be okay – the
builders trusted in the power of communication.
While conceding that the process is not always perfect, Gawande
praises the construction industry, pointing out that its “record of success has
been astonishing,” building millions of complex commercial and residential
buildings with very low rates of failure. Gawande attributes this success
to the power of the construction planning process to integrate the specialized
knowledge of architects, engineers, manufacturers, and skilled trades into the
project and to ensure that all of these specialists communicate on complex
problems.
As
construction lawyers who often dwell on the things that go wrong on
construction projects, it is useful to step back and consider how often things
go right, and why. Gawande’s book is aimed primarily at promoting the use
of checklists to reduce medical errors.
He encourages the medical field to adopt some of the processes used by
the construction industry to build complex buildings. The construction industry, in turn, can
benefit from his book by asking how to further improve these checklists to
avoid persistent defects and quality issues.
