Most lawyers overestimate the strength of the current market for law firm services, and that is partly why big law firms have for years failed to respond to client demands for efficiency.

As a result, many firms are increasingly vulnerable to losing work to in-house lawyers and newer, more nimble competitors. Those are the conclusions from an annual report by the Thomson Reuters Legal Executive Institute and the Center for the Study of the Legal Profession (CSLP) at the Georgetown University Law Center.

The CSLP and Thomson Reuters report states that law firms can still succeed in today's market by changing their approach to pricing, managing work and implementing technology as part of an effort to deliver more efficient services.

"Our hope with this is that we can help build a kind of wake-up call," said James Jones, an author of the report and former managing partner of Arnold & Porter, who now serves as a senior fellow at Georgetown's CSLP. "Because in point of fact, I think that law firms can have a real competitive advantage and be significantly successful if they will only do some of this basic stuff."

The 19-page report, which focuses on the top 200 US law firms, includes market data from up to November 2017 from Thomson Reuters Peer Monitor. The latest report includes the finding that demand across all law firms experienced virtually zero growth last year. Am Law 100 firms, however, saw demand growth of more than 1%, while Am Law Second Hundred firms saw demand fall by more than 1%.

The top 100 firms also increased their agreed-upon rates by about 3.7% last year. The Second Hundred increased those rates by 2.8%, according to the report.

While the data depicts a continued stagnant market for high-end legal services, the report is more broadly a diagnosis of the ailments – often psychological in nature – that have prevented firms from responding to the realities of a changing legal market.

The CSLP and Thomson Reuters report states that firms in many cases remain committed to "once-successful strategies even as evidence mounts of their failure". Citing an article from the Harvard Business Review titled, "Stop Doubling Down on Your Failing Strategy", the report discusses natural human biases that can paralyse leaders.

Those include 'the sunk cost fallacy', which leads people to see through investments to their completion rather than to cut and run when it is clear those investments will not pay off. Another is 'personal identification', something that prevents leaders from changing course because their reputation is perceived to be tied to a previous strategy.

Ignoring strong indicators that their old approaches are no longer working, law firms choose to double down on their current strategies

The report claims that these biases can lead managers to ignore the events that undermine a strategy and double down on their decisions to justify their prior actions, a phenomenon called 'consensual neglect'.

"'Consensual neglect' seems a particularly apt description of the strategic posture of many (if not most) law firms in today's rapidly changing market for legal services," states the report. "Ignoring strong indicators that their old approaches – to managing legal work processes, pricing, leverage, staffing, project management, technology and client relationships – are no longer working, they choose to double down on their current strategies rather than risking the change that would be required to respond effectively to evolving market conditions."

One reason firms may neglect a changing market, according to the report, is that many of the industry-wide statistics conceal just how much the market has changed.

While the theme of a widening gap between the Am Law 100 and Second Hundred has previously been reported, the CSLP and Thomson Reuters report states that less is understood about how much variation exists among firms even in those groups.

Citing research by Bruce MacEwen of Adam Smith Esq, the CSLP and Thomson Reuters report notes that of the $3.5bn in nominal increases in Am Law 100 gross revenue reported in 2017, two thirds of that sum can be attributed to about 20 of the 100 firms.

If gross revenue growth is increasingly limited to a handful of firms, the report claims those firms as a whole are far less profitable than most think. Pointing to a story written last year by Chris Johnson, former chief global correspondent for The American Lawyer, the report states that law firm profitability metrics fail to account for the cost of equity partners' salaries. Adjusting for that, Johnson found the average profit margin for the Am Law 200 would fall from 38% to about 14%.

"What is becoming increasingly clear is that the market in which law firms are required to operate today may in reality be quite different from the one that most law firm partners have fixed in their minds," states the  report. "So far, the realignment of competition across the legal industry has been limited, but the direction of movement is clear and the pace of change is accelerating."

The report predicts faster growth for alternative legal service providers such as Axiom, Consilio and UnitedLex, the latter of which made headlines in December with a deal to outsource a portion of the legal department of publicly traded DXC Technology.

A Thomson Reuters report last year showed the market for alternative legal service providers (ALSP) had grown to $8.4bn, compared to a $275bn US market for legal services and a $700bn market worldwide. But Jones, the CSLP senior fellow and a legal industry consultant, said the size of the ALSP market should not be underestimated.

"If we see ALSPs continue to grow at the rate they have in the past – and some were growing at 25%-30% per year – it's not going to be very long before they take a significant chunk," Jones said. "And I would argue that $8.5bn is already a pretty big chunk."

Still, Jones said he was "not really pessimistic" about the prospects for law firms. He said competition for the "middle 60%" of legal work will grow increasingly fierce as the top firms more exclusively service the top 20% of high-end work and in-house departments keep the bottom 20% to themselves.

"To get to that 60%, given the types of competitors in the market, firms are going to have [to] work differently," Jones said. "They'll need to have different staffing models, be more multidisciplinary in the market. And that's the hard part. But I'm optimistic that those that do will meet with some success. And the record indicates that."
