Untangling Tangled Threads
by Rick Brenner
In energetic discussions, topics and subtopics get intertwined. The tangles can be frustrating. Here's a collection of techniques for minimizing tangles in complex discussions.
hen controversy is in the air, or the group is large, the flow of discussion in meetings can become confused and tangled. Even when facilitators manage queues of contributors, separations between related contributions grow, threads proliferate, and people forget what they wanted to say as they are overtaken by events.

A senator rests on a cot in the Old Senate Chamber during a filibuster. A filibuster is a tactic used to delay any action of a deliberative body, usually employed by a minority that is otherwise unable to prevail with regard to the question at issue. In the US Senate, a 60% majority is required to halt a filibuster, even if the question on the table requires only a simple majority for passage. During the period in which the photo was taken, filibusters automatically ended if the minority failed to speak continuously, which led to the need for cots to enable weary senators to snatch naps between speeches.
Some of the content of extended discussions in meetings can arise for similar reasons: a vocal minority might wish to prevent the majority from taking action it opposes. In businesses, executive decision often prevails, but when a group prefers to operate by consensus, delaying tactics are sometimes the underlying cause of thread tangling.

When the
threads of discussion become tangled, the group's decision quality degrades. Reaching decisions becomes a long, painful process. How can we keep threads from tangling, or untangle them when they tangle?
- Use a parking lot
- Sometimes a collection of contributions isn't really essential to the current discussion. Or perhaps it's important, but missing information or absent staff prevent a definitive conclusion.
- Threads of this kind can be profitably deferred using a technique widely known as the parking lot. Deferring the topic by adding it to a parking lot, or issues list, clears the table, making way for the larger discussion to move forward more effectively.
- Identify questions masquerading as assertions
- One common source of controversy is the question masquerading as an assertion. Some contributions are assertions or conjectures that, although possibly correct, are nevertheless unproven. When controversy is in the air, these contributions tend to generate much energy but little light.
- By identifying statements that are actually open questions, the group can focus its discussion on resolving the questions, possibly at a later date, rather than endlessly circling around a loop of assertions and counter-assertions.
- Name and rank the threads
- Once a collection of contributions emerges as a thread, allowing it to continue as a part of the ongoing discussion creates a risk that it will tangle with other threads.
- By giving each thread a name, and setting priorities for each, the group or its facilitator can give focus to a single thread, temporarily setting others aside. This leads to a more orderly discussion.
- Maintain multiple queues
- Once you've named threads, and ranked them, arriving contributions can be queued independently for any threads that aren't currently under discussion. Maintain a separate queue for each thread.
- This scheme is more effective when participants make notes for themselves about the contributions they intend to make to threads that have been temporarily set aside.
If a single thread, or a
collection of threads, becomes
complex enough, it merits
a discussion of its own
- Spin off independent discussions
- If a single thread, or a collection of threads, becomes complex enough, it merits a discussion of its own. To keep it as part of the discussion that spawned it entails risk of confusion.
- Make it an agenda item, at this meeting or at a future meeting. Accomplishing this might require deleting or postponing other items from the existing agenda.
Even these measures have limits. Large groups engaged in especially controversial conversations might have to break into smaller caucuses, in parallel or in series, to address the most contentious issues. Groups that can't agree on how to manage their discussions probably can't agree on much else. First in this series

- Person-to-Person Communication for Project Managers
- When
we talk, listen, send or read emails, read or write memos, or when we leave or listen to voice mail messages, we're communicating person-to-person. And whenever we communicate person-to-person, we risk being misunderstood, offending others, feeling hurt, and being confused. There are so many ways for things to go wrong that we could never learn how to fix all the problems. A more effective approach avoids problems altogether, or at least minimizes their occurrence. In this very interactive program you'll learn a model of inter-personal communications that can help you stay out of the ditch. In those moments of intense involvement, when we're most likely to slip, you'll have a new tool to use to keep things constructive. Read more about this program.

December 1911, four men led by Roald Amundsen reached the South Pole. Thirty-five days later, Robert F. Scott and four others followed. Amundsen had won the race to the pole. Amundsen's party returned to base on 26 January 1912. Scott's party perished. As historical drama, why this happened is interesting enough. Lessons abound. Among the more important lessons are those that demonstrate the power of the agile approach to project management and product development. Read more about this program.

- Human-Centered Risk Management
- Most
of us can assess technological risks, but risks related to human behavior tend to resist our best efforts. This session provides a framework for evaluating risks related to the behavior of individuals, teams, organizations and people generally. Human-centered risk differs from technological or market risk, because objective evaluation requires acknowledging personal and organizational limitations and failures. Since some of those limitations and failures might apply to the people assessing the risks, or to their superiors, there's a tendency to deny them or to explain them away. Our approach examines capability, organization, context, risk mitigation, and workplace politics. It has tools for guiding the assessment and management of human-centered risk, and we show how to extend these tools to suit your situation. You'll learn how to identify sources of risk in human behavior; recognize systemic and individual barriers to acknowledging risk; assess the effects of organizational turbulence; determine the risk associated with inappropriate internal risk transfer; estimate the effects of team dysfunction, toxic conflict and turnover; and measure the impact of workplace politics.

- Project Management in Fluid Environments
- Most
people now work in environments that can best be characterized as fluid, because they're subject to continual change. We never know what's coming next. In such environments, managing — teams, projects, groups, departments, or the enterprise — often entails moving from surprise to surprise while somehow staying almost on track. It's a nerve-wracking existence. This program provides numerous tools that help project managers who work in fluid environments. Read more about this program.

's a lot more to running an effective meeting than having the right room, the right equipment, and the right people. With meetings, the whole really is more than the sum of its parts. How the parts interact with each other and with external elements is as important as the parts themselves. And those interactions are the essence of politics for meetings. This program explores techniques for leading meetings that are based on understanding political interactions, and using that knowledge effectively to meet organizational goals.
