It’s conventional wisdom that the way for a firm to build its stature is to broaden its set of practice offerings. I hear partners say things like “All the top firms have a New York corporate practice; we should have one too” or “Great firms like Latham have tons of practices; we need to be like those guys”.

This is nuts. Or, to be polite, this is counter to what the data show. Take a look at Figure 1. It examines 2007 Chambers rankings and shows, for each ranking band, the percent of firm rankings that were in the same or higher band a decade later, i.e. the percent that sustained or improved their band ranking from 2007 to 2017, (details of the calculation in “About the analysis” below). The data show that stronger practices are more sustainable: the higher the band, the greater the probability of a firm’s ranking holding or improving. For example: while two-thirds of Band 1 rankings were held, barely one-in-ten Band 4 rankings were held or rose, (i.e. 90 percent of practices in Band 4 had descended to Band 5, or were no longer ranked, a decade later). Although the analysis here looks at practice strength for those achieving Chambers USA Nationwide status, the same dynamics likely hold in other domains: the stronger the practice, the more likely it is to sustain or gain in strength.

These dynamics have important implications for how firms should think about investing to augment their stature. Broadly, a firm has two options: add breadth (build new practices) or add depth (push existing practices up the ranking bands). If a firm chooses to add breadth, they’ll start with something like a Band 4 position. But such positions are precarious; there’s a 90 percent chance the position will be lost in 10 years. You can picture how this plays out in the real world: a firm makes a splash by hiring partners laterally in the new practice area. But integrating laterals and cementing them to their new firms is tricky. Firm management often expects the laterals to port more business, more quickly, than they do; laterals expect management to invest more, more quickly, than the firm does. Disappointment abounds; momentum is lost; the new laterals move on—half of all laterals stay barely five years at their new firms; the move-on rate is doubtlessly higher for those in add-on practices.

The ‘add depth’ option has more promise. Practically, it takes the form of bolstering existing practices by having leaders spend more time focusing on the needs of the partners spearheading their growth, promoting more partners, bringing partners in laterally around the positions of proven strength, adding to the senior associate and counsel cohorts, and (crucially) investing in business development and practice support professionals. It’s not sexy, it doesn’t give rein to leaders to act like I-bankers, but it works: bolstering the status of an existing practice makes the practice more sustainable.

Importantly, strengthening existing practices has a benefit more compelling even than improved stability: it drives higher profitability growth. Figure 2 shows the percent of ‘hold-or-rise’ rankings by firm (on the horizontal axis) and growth rate of profit-per-equity partner, PPP, (on the vertical axis) for firms with ten or more practice rankings in 2007. There are 23 firms that evidence a clear trend of increasing PPP growth with growing ‘hold or rise’ percent, and a group of 5 outliers above the trend-line. It’s never easy to identify what distinguishes outliers in macro analyses like this. That said, Kirkland can be argued to have redefined how a law firm can grow and increase profits, and it’s noteworthy that Fried Frank, Wilmer, Weil, and Holland & Knight reduced their equity partner headcount over the period by 24, 20, 14, and 8 percent, respectively; this would facilitate their per-equity-partner profitability outpacing the effect of band rankings alone.

This picture of stronger practices leading to greater sustainability which in turn leads to higher profit growth is evidence of the “great lawyers – great clients” dynamic that is the core of law firm strategy (see Figure 3): great lawyers attract great clients to a firm; having great clients retains, and attracts even more, great lawyers; having more great lawyers in turn attracts yet more (and more work from) great clients; and so it repeats—a self-reinforcing loop. It’s the same dynamic as at the heart of eBay: the buyers come because they know that is where the sellers are; the sellers come because they know that is where the buyers are. This dynamic keeps competitors out through a Catch-22: they don’t have the lawyers to attract the great clients; and they don’t have the clients to attract the great lawyers. Making it hard for would-be competitors enhances sustainability, augments price realization and drives superior profit growth.

Clearly the higher return option in terms of stability and profit growth is to invest for practice depth not breadth. But what’s a firm to do if it starts with a portfolio of practices that has extensive breadth without commensurate depth, such as in the bottom right quadrant of the matrix in Figure 4? Many firms try to strengthen such portfolios by building practice depth across all practices simultaneously, i.e. to climb vertically from the bottom right cell to the top right cell in the matrix. This is a tall order. The prospect for an investment initiative paying off increases with the amount invested; hence, for a given capacity to invest, the narrower the set of initiatives invested in, the higher the prospects for success. Thus, the way for most firms to build sustainable, high profit-growth, practices is first to narrow their set of practices (move to bottom left) and then to invest for depth in the more-focused portfolio of practices (move to top left). Only once a set of deep practices has been established should that set be expanded (more to top right). Thus, the path to increased firm stature is to follow the “C-curve” shown.

Closing thought

The next few years will be challenging for Big Law. The coming recession will exacerbate the disruption caused by the secular increase in client in-sourcing and technology evolution. It’s more important than ever to be thoughtful, even circumspect, about a firm’s portfolio of practices. On this, the evidence is clear: narrow and deep triumphs over broad and shallow.


About the analysis

The analysis examined the 40 practice areas in the 2007 Chambers USA Nationwide Rankings that were defined in (essentially) the same way in 2007 and 2017. These comprise 627 rankings across 175 firms. A complication in the ‘hold or rise’ calculation stems from grade deflation in the Chambers rankings during this time period. As Figure 5 shows, the number of firms ranked in Bands 1 and 2 fell over the period, that in Band 3 rose slightly, while those in Bands 4 and 5 rose substantially. The analysis backs out this deflation by adjusting the number of surviving firms by a factor equal to the inverse of the ratio of new-to-old firms in the relevant bands. For example, there were 151 Band 1 rankings in 2007; of these, 84 were also Band 1 in 2017. However, over the period, the total number of Band 1 rankings fell to 128, a decline to 84.8 percent of the 2007 number (151). To adjust for this decline, the number of maintained Band 1 rankings in 2017 (84) is augmented by a factor of 1/0.848 to yield the grade deflation-adjusted number of 2017 rankings (99), which in turn yields a 65.6 ‘hold or rise’ (99/151) percentage. The same adjustment is applied to lower bands by looking at the cumulative number of rankings from Band 1 down.
