Creating Value:The Social Capital of Leaders

The shift to less hierarchical companies and global markets has triggered a shift from vertical chains of command to horizontal linesof cooperation. Business leaders have a choice between two strategies for adding value: Brokerage is a strategy for creating value,cohesion is a strategy for delivering on a known value stream. This session is about the first strategy, brokerage. It is about successfulleaders who read organizations and markets to figure out what to do, and who to involve in getting it done. Such leaders have socialcapital. This session is about what it means to have social capital, and how having it is linked to value. The following sequence ofquestions will be addressed:

What is the structure of a high-value-add organization, and how does it depend on financial, human, and social capital?

What is the distinction between human and social capital, and how does each enhance leader performance? In other words, what iswrong about the following famous quote:

“If a man can write a better book, preach a better sermon, or make a better mousetrap than his neighbor, though he buildshis house in the woods, the world will make a beaten path to his door.”

How do leaders thrive even if they don’t have direct control over the resources needed to deliver on their ideas?

What is it about successful leaders like John Clendenin that most irritates (perhaps one could say “frightens”) the people around them?

Assessing the Value of Affymax

1988 Affymax Research Institute founded by Dr. Alejandro Zaffaroni toaccelerate the drug discovery process.

1991 Affymax IPO as leader in the field of combinatorial chemistry

1995 Affymax and its holdings in spin-offs acquired by Glaxo-Wellcomein a buy-out valued at $485 million.

2000 Glaxo-Wellcome receives $500 million for reducing its 65%interest in spin-off Affymetrix to 16%.

2001 Affymax Research Institute re-emerges as an independentcompany when a syndicate of venture capital firms led byPatricof & Co. Ventures purchases GlaxoSmithKline's interest inAffymax.

The employee AFTER is more positioned

at the crossroads of communication

between social clusters within the firm

and its market, and so is better

positioned to craft projects and

policy that add value across

clusters.

Here is the core network for a job BEFORE and AFTER the employee

expanded the social capital of the job by reallocating network time and

energy to more diverse contacts.

Research shows that

employees in networks

like the AFTER network,

spanning structural holes,

are the key to integrating

operations across functional

and business boundaries. In

research comparing senior people

with networks like these BEFORE and

AFTER networks, it is the AFTER networks

that are associated with more creativity, faster

learning, more positive individual and team

evaluations, faster promotions,

and higher earnings.

*Network scores refer to direct contacts.

It is the weak contact connections (structural holes) in

the AFTER network that provides the expanded social

capital.

Evidence Categories on Bridging Structural Holes

from Burt, "The social capital of structural holes" (2002, The New Economic Sociology).

Bridging structural holes increases the probability of accidental learning, which increases

the odds of distinguishing valuable bridges from trivial bridges (else bridges are merely

socializing or costly bureaucracy). Network entrepreneurs are a guidance system that

deploys corporate and market resources to places in which the resources create value.

Brokerage

Structural Holes

Creativity & Learning(What should be done?)

Achievement & Rewards(What benefits?)

Adaptive Implementation(Who should be involved?)

Adaptive Implementation — John A. Clendeninat Xerox

The case for discussion is Clendenin’s management of the Multinational DistributionCenter (MDC). After a stint in the Marine Corps and graduation from business school,Clendenin joined Xerox in 1984. A series of successful projects earned Clendeninpromotion in December 1984 to administrative manager for the parts and supplyarea. He found, hidden away within his domain a small subunit, the MultinationalSystems Development Center (MSDC), which was responsible for developing andmaintaining systems to improve communication between the logistics and distributionoperations within each of Xerox's worldwide operating units. Though not viewed asan important part of Xerox’s operations, the MDSC was responsible for tracking the distribution of Xerox’s $8 billion per year in copiersand spare parts from 23 manufacturing plants in 15 countries. Analyzing the existing system, Clendenin calculated that the MSDC hadthe potential to reduce operating costs by approximately $100 million per year.

Clendenin builds the social capital of the MDC and himself over the subsequent years. Managing through the self-interest ofothers, he nurtures subordinates in a lively, competitive work environment, and adds value to internal clients with cost reductionprograms that coordinate across the structural holes between Xerox’s regional logistic operations. The result is a quotable successstory: The MDC grows from four to 42 people before Clendenin is rotated in 1989 into a new management position in logistics. TheMDC’s budget grows from $400K to $4.3M. Over Clendenin’s tenure, his organization is credited with taking $700M in inventory costsout of Xerox’s operating expenses, reducing the company's $2.6B supply-chain spend down to $1.9B.

Case Discussion Questions*

1. Clendenin seems to be a master at creating resources where none existed before (for example, thegrowth of the MDC). How does he do it?

2. Would you want to work for someone like Clendenin? What are the benefits? Disadvantages?

3. Would you hire someone like Clendenin to work for you in your organization? How do you managethis kind of talent?

*Photo is from the video shown during the session.More detail can be obtained from “Managing Xerox’s Multinational Development Center” (Harvard Business School Press, case number 9-490-029).

The Social Capital of Leaders

Three Session-Summary Points1. THERE IS A SOCIAL ORDER TO ORGANIZATIONS & MARKETS

For reasons of opportunity (largely location), shared interests and experience, and simple inertia, organizations andmarkets drift toward the bridge and cluster structure illustrated on page 5. This is the social structure across whichbusiness leaders strategize about what to do and with whom to do it.

2. VISION ADVANTAGE OF BROKERAGE CONCENTRATES VALUE AROUND THE BRIDGES

Structural holes are the metric for social capital. Brokerage across holes creates a vision advantage (better see whatto do, who to involve). The result is that social capital increases with the diversity of your contacts. If everyone youknow is well-known to one another, you don’t have social capital. Ceteris paribus, BROKERS DO BETTER (asillustrated on page 10).

3. REPUTATION IS CRITICAL, WHICH CREATES A MANAGEMENT PROBLEM

Uncertainty is the primary impediment to exercising social capital (and a focus this afternoon). Top managementdepends on able employees using social capital to search out and implement ways to add value for the organization,but too much puts the enterprise at risk. Company chains of command broken in service of company interests can justas easily be broken in service of personal interests, or in service of well-intentioned but strategy-eroding interests.* Thetwo cases this morning illustrate reputation effects:

Zaffaroni case illustrates the importance of reputation within and beyond the team for establishing connectionsbetween groups within a team,

Clendenin case illustrates the importance of reputation for overcoming the suspicions with which brokers are viewed(recall Les Elstein and the distrust of Clendenin's motives expressed in this session).

Network constraint measures the extent to which your network is concentrated

in a single contact. There are two components: (direct) person consumes a large

proportion of your network time and energy, and (indirect) person controls

other people who consume a large proportion of your network time and energy.

Recent years have seen a dramaticshift in the way companiesorganize. The shift is away frombureaucracy. Layers of formalcontrol within and across functionsare being replaced with fewerlayers of negotiated informalcontrol.

The shift away frombureaucracy means that managerscannot rely as much on directivesfrom above. They are now morethan ever the authors of their ownwork. The upside is that firms canidentify, and adapt more readily to,needed production changes andmarket shifts. The downside isnew costs for managers. Thecoordination costs once borne bycorporate bureaucracy — eachperson having responsibility forcoordination within a limited

develop needed skills in a broaderrange of younger managers, (c)identify the right people to managecross-functional teams andtransitions from the old to the new,(d) understand diversity issues, and(e) anticipate catalysts andbottlenecks to organization change(i.e., how reengineering,downsizing, merging, acquiring,and the like will be received by theorganization).

There are two ways tounderstand social capital; relativeto human capital, and as a form ofnetwork structure.

SOCIAL CAPITAL RELATIVETO HUMAN CAPITALHuman capital and social capitalarguments explain why some

capital refers to opportunity.Managers with more social capitalget higher returns to their humancapital because they can identifyand develop more rewardingopportunities.

SOCIAL CAPITAL AS A FORMOF NETWORK STRUCTUREStructural hole theory givesconcrete meaning to the socialcapital metaphor. Hole theorydescribes how the structure of anetwork is a competitive advantagefor certain people over others. In aperfect market, one rate of returnclears the market. In an imperfectmarket, there can be multiple ratesof return because disconnectionsbetween individuals, holes in thestructure of the market, leave some

structures rich in disconnectionsbetween people are rich in theentrepreneurial opportunities ofstructural holes.

People better connectedacross structural holes are betterpositioned to broker otherwisedifficult or unlikely exchanges, andso are likely to enjoy higher returnsto their human capital. Specifically,managers with contact networksrich in structural holes are theindividuals who know about, have ahand in, and exercise control over,more rewarding opportunities.They have broader access toinformation because of their diversecontacts (information access benefitof holes). That means they aremore often aware of newopportunities, and aware earlierthan their peers (information timing

Robert took over James' job. Entrepreneurial Robert expandedthe social capital of the job by reallocating network time and energyto more diverse contacts.

Research shows that peoplelike Robert, better positioned forentrepreneurial opportunity, are thekey to integrating across functions andacross the people of increasingly diverse backgrounds in today's flatterbusiness organizations. In research comparisons between managerslike James and Robert, it is the people like Robert who get promotedfaster, earn higher compensation, and perform more successfully on teams.

It is the weak connections (structural holes) between Robert's contacts that provide his expanded social capital. Robert is more positioned at the crossroads of communication between social clusters within his firm and its market, and so is positioned to craft business policy to add value across clusters.

The Social Capital of Entrepreneurial Managers

From 5/10/96Financial Times(EuropeanEdition)

Ronald Burt is theHobart W. WilliamsProfessor ofSociology andStrategy at theUniversity of ChicagoGraduate School ofBusiness. His theoreticalwork describespreference formationand entrepreneurialopportunities incompetitiveenvironments. Applications focuson the contactnetworks of high-performancemanagers (how peopleof diversebackgrounds createsocial capital) and thenetwork structure ofmarket profits (howthe structure ofproducer, supplier,and customer relationsdefines competitiveadvantage amongproducers).

domain of responsibility — arenow borne by individual managerswho have responsibility forcoordination across broaderdomains of business activity.

Which is why the adageabout working through others istaking more concrete form atleading business schools. Socialscience has made striking advancesin theory and research over the lasttwenty years on the principles ofadding value through other people.The core concept is social capital,the University of Chicago is at thefrontier of theory and research onthe issue, and the GSB is at thefrontier of crafting courses thatbring the work to the classroom.

Managers differ in theirability to survive and thrive withoutbureaucracy. What is anopportunity for some managers, isdistress for many others.Coordination tasks are nowbroader, with a correspondingincrease in uncertainty, stress, andpotentially disruptive conflict.New issues emerge for humanresource management.

Which is why social capitalanalysis can be useful. In socialscience terms, the shift away frombureaucracy is a shift to socialcapital as a critical performancefactor. Social capital refers to thewealth of a manager’s relationshipswithin and beyond the firm. Thisform of capital can be measured,and enhanced, so analysis can be apowerful tool in human resourcemanagement. Specifically, socialcapital analysis has been useful to:(a) understand how a companyreally works (how peoplecommunicate, how informationflows, and so on), (b) identify and

managers add more value to theircompanies. Both arguments beginwith inequality. Some managersenjoy higher incomes. Some arepromoted faster. Some are leaderson the more important projects.The human capital story is thatsuch inequalities result fromdifferences in individual ability.The more rewarded managers aresmarter, or better educated, or moreexperienced.

Social capital focuses on thevalue a manager adds through otherpeople. The social capital story isthat inequalities result fromcontextual differences betweenpeople. Returns to intelligence,education, and seniority depend ona manager’s location in the socialstructure of an organization. Someportion of the value a manager addsto a firm is his or her ability tocoordinate other people, wherecoordination refers to identifyingopportunities to add value withinan organization, and getting theright people together to takeadvantage of the opportunities.Certain network structures ofrelationships — deemed socialcapital — can enhance a manager’sability to identify and developopportunities.

The summary points aretwo: (a) Social capital differs fromhuman capital. Social capital is aquality created between peoplewhile human capital is a quality ofindividuals. Investments thatcreate social capital arefundamentally different from theinvestments that create humancapital. (b) Social capital is thecontextual complement to humancapital. Where human capitalrefers to individual ability, social

managers unaware of the benefitsthey offer one another. Certainmanagers are connected to certainothers, trusting certain others,obligated to support certain others,dependent on exchange with certainothers.

In the above diagram, Jameshas a network that spans onestructural hole (the relatively weakconnection between a clusterreached through contacts 1, 2, and 3versus the other cluster reachedthrough contacts 4 and 5). Thestructural hole between the twoclusters does not mean that peoplein the two clusters are unaware ofone another. It simply means thatpeople in each cluster are sofocused on the press of businesswithin their own cluster that theypay relatively less attention to theactivities of people in other clusters.

Robert took over James' job.Robert preserves connection withboth clusters in James' network, butexpands the network to a morediverse set of contacts. Robert'snetwork, adding three new clustersof people spans ten structural holes.

These structural holesbetween people are entrepreneurialopportunities for third parties tobroker the flow of informationbetween people on opposite sides ofthe structural hole, and control theform of projects that bring togetherpeople on opposite sides of thestructural hole. Structural holesseparate nonredundant contacts.Each hole is a buffer, like aninsulator in an electric circuit. As aresult of the structural hole betweenthem, two contacts provide network(information and control) benefitsthat are in some degree additiverather than overlapping. Social

benefits). They are also more likelyto be the people discussed assuitable candidates for inclusion innew opportunities (referralbenefits). They are also more likelyto have sharpened and displayedtheir capabilities because they havemore control over the substance oftheir work defined by relationshipswith subordinates, superiors, andcolleagues (control benefits). Thesebenefits reinforce one another atany moment in time, and cumulatetogether over time.

Through theirentrepreneurial opportunities,managers with contact networksrich in structural holes can addvalue above and beyond the valueof their human capital. Theymonitor information moreeffectively than bureaucraticcontrol. Gossip moves faster, andto more people, than memos.Entrepreneurial managers know theparameters of organizationproblems early. They are highlymobile relative to bureaucracy,easily shifting network time andenergy from one solution toanother. Entrepreneurial managerstailor solutions to the specificindividuals being coordinated,replacing the boiler-plate solutionsof formal bureaucracy. To thesebenefits of faster, better solutions,add cost; entrepreneurial managersoffer inexpensive coordinationrelative to the bureaucraticalternative. In short,entrepreneurial managers operatesomewhere between the force ofcorporate authority and thedexterity of markets, rushingcoordination to disconnected partsof the firm that could beproductively brought together.
