From Chapter 1: Introduction

It is 09:30 India Standard Time, and Kuldeep, a software engineer in information technology (IT) production support is frustrated. He cannot re-create the software defect based on what was logged into the issue/defect system during the night. He has no one to call. The author of the defect report, an American who lives and works 10.5 time zones away, is now sleeping. So the Indian software engineer resorts to writing a lengthy e-mail requesting clarification. Solving the problem is delayed by one day… at the very least. 
The coordination breakdown represented in this vignette stems from time zone separation. There are countless others like it in many knowledge professions. While such coordination breakdowns are common today, these time zone challenges are relatively new. Until the 1980s, time zone separation did not matter much. Sure it mattered for airline pilots and ministers of foreign affairs, but for the vast majority of knowledge workers, it had little impact on daily work. Then, in the 1980s, the fax machine became a ubiquitous form of communication. This made it possible for some work objects—documents, designs, accounts and programs—to be transferred instantly across time zones.
Still, even into the mid-1990s, geographic distance was more important than time zone differences because shipping a work object took days and cost a lot of money. In that ancient era, software professionals air-shipped floppy disks and magnetic tape reels inscribed with computer code. Coordination between distant collaborating sites was, at best, what we could call loosely coupled. Yes, the sites were interdependent, but not much.

Then the Internet came along and, all of a sudden, time zone differences mattered.

Glossary of Terms

A software development approach that emphasizes client collaboration, team member interaction, and quick iterations. See chapters 3, 7.

async--Short for asynchronous, meaning not at the same time. See also “sync.”

average handle time--A call center metric for the average duration of one transaction of client call. See chapter 6.

bridged--One of the six basic time zone configurations. In this configuration, one liaison bridges/ overlaps distant sites in two time zones. See also “East–West.” See chapter 2.

clustered--One of the six basic time zone configurations. In this configuration, members work in various locations and time zones, but there is one central dominant site/time zone where a large percentage of members are located. See chapter 2.

cold spots--The unscheduled time around which family and friends can enjoy themselves. See chapter 8.

co-located--One of the six basic time zone configurations, in which all team members reside at the same location. See chapter 2.

conventional global approaches--Parallel or phase-based, as opposed to the "Follow-the-Sun" approach. See chapter 6.

conveyance processes--The transmission of new information to enable the receiver to create and revise a mental model of the situation. See chapter 10.

coordination tactic--A mechanism or process used by collaborators. There are three types: mechanistic (based on processes and routines), organic (based on communication), and implicit (based on collaborators’ knowledge). See also “coordination mix.” See chapter 10.

coordination--The management of dependencies among task activities. Alternative definition: the act of integrating each task and organizational unit so that it contributes to the overall objective. See chapter 10.

convergence--Collaborators across time zones coming together, to create, to agree, to build the same “mental model” in their heads and resolve any miscommunication. See chapter 3.

convergence window--The overlap time window between individuals and sites, across time zones, which is used for converging, typically by voice, on work issues. See chapter 3.

distraction science--A new specialty discipline about how people focus on tasks and get distracted from tasks. See chapter 9.

distributed work--Work by teams and/or individuals who are not at the same location. See chapter 1.

DST--Daylight Saving Time. A region moves the clock forward during summer. DST narrows/widens time separation with locations that do not have DST. See chapter 1.

GMT--Greenwich Mean Time.

granular--Small size tasks that can be handled quickly; for example, helpdesk tasks, which may be handled in a few minutes. For granular work, there is little coordination challenge in handing-off work between various global sites since the sites do not hand-off much half-finished work.

handoff--The handoff transfers and resolves the essential information for all unfinished work. We recommend that the handoff have both written and verbal components. See chapter 3.

hot spots--Scheduled commitments such as work, sleep, chores. See chapter 8.

implicit coordination--The coordination based on unspoken assumptions about what others are likely to do; achieved from knowledge team members have about each other and about the task activities of others in the team. See chapter 10.

internal interruptions--The situations in which we stop the work we are doing with no apparent external cause. See chapter 9.

nomadism--The subculture of working anywhere. Many nomads work in caf├ęs, in “third places,” not their home or office. See chapter 1.

organic coordination--Individuals communicate naturally, often unscheduled, in order to coordinate and problem-solve. This is one of three coordination tactics. See also “coordination tactics.” See chapter 10.
