Scrum Master Toolbox Podcast: Agile Storytelling from the Trenches

Episode: Managing Dependencies and Downstream Bottlenecks in Scrum
Date: October 15, 2025
Host: Vasco Duarte
Guest: Renee Troughton

Overview

This episode dives deep into one of the thorniest issues in scaled Agile environments: managing dependencies and bottlenecks—especially as they affect downstream teams that often get overlooked during high-level planning. Vasco Duarte and guest Renee Troughton, a seasoned Agile coach, explore real challenges, share tried strategies, and emphasize the importance of prioritization, systemic thinking, and an experimentation mindset.

Key Discussion Points and Insights

Challenge Overview: Downstream Dependencies

• Renee’s Context: Organization with dozens of teams across business lines; quarterly planning is "pretty high level," leading to downstream teams (e.g., middleware, data, AI, legal) being neglected until their input is urgently needed.
  • "Downstream teams … end up having a huge amount of unexpected work … leads to them having lots of peaks and troughs." (02:20, Renee)
• Shared services and non-product teams often lack visibility and involvement in early planning and discovery.

The Planning “Swing”

• Organizational Pattern Identified:
  • Teams oscillate between minimal planning, which is "just enough to get started," and excessive planning that delays work.
  • Some organizations swing between Agile and traditional project management repeatedly, seeking the 'perfect' level of upfront certainty.
  • "I'm reminded of an organization...currently...going through their third agile adoption, where every time they adopt Agile, then they go back to project management … then go back to Agile. ...the third time back to Agile." (04:16, Vasco)

The Real Bottlenecks

• Who Suffers Most?
  • Product teams are generally comfortable with ambiguity and incremental work.
  • Downstream teams (service/shared services) are under-resourced and become a bottleneck within the delivery flow.
  • Key metaphor: "Imagine several rivers flowing into one main river…"—upstream teams all “flood” the downstream team at once. (06:59, Vasco)
  • “100%. Yes, exactly.” (08:19, Renee, on the flood analogy)

Experiments and Strategies in Play

1. Organization-Wide Initiative Prioritization

• Stack ranking initiatives at the top level to make dependencies and priorities visible to all teams.
• Holding regular (weekly/fortnightly) prioritization forums with shared service teams.

2. Capacity Buffering

• Reserving unallocated capacity for known-but-unplanned demand, using historic data to estimate needed buffers.

3. Proactive Dependency Identification

• Engaging tech leads earlier in work discovery to alert downstream teams about upcoming work.
• “Trying to get tech leads…to say, I actually identify there is a downstream dependency…and then connecting the dots.” (09:17, Renee)

4. Spreading Work Across Quarters

• Staggering workload so not all downstream demand hits at once; e.g., some product teams plan work for different months of the quarter to create a steady flow.

5. Shared Code Ownership & Upstream Responsibility

• Encouraging product teams to own more of the changes (with support from shared service teams as advisors), reducing bottlenecks at the downstream teams but preserving architectural consistency.

6. Theory of Constraints Approach

• Recognizing and actively managing the bottleneck to keep the flow optimal rather than overloading it.
• “We control the flow of work into the bottleneck … so that the bottleneck is never overworked.” (10:35, Vasco)

7. Non-Technical Bottlenecks

• Acknowledgment that constraints are not always technical—e.g., legal can be a bottleneck.
• Leadership-level discussions to prioritize and consciously defer some requests, or accept greater risk for faster outcomes.
• “Let’s do a bare bones answer … we’ll take the risk on as a business as a consequence.” (12:57, Renee)

Notable Quotes & Memorable Moments

• On ambiguity and comfort levels:
  "For the actual, let's say product teams, it's not a problem for them. I feel like they are comfortable with the ambiguity … It's more the downstream teams that aren't the product teams…" (05:45, Renee)

• On repeating Agile/PMO cycles:
  "…every time they adopt Agile, then they go back to project management … back to Agile … the third time back to Agile." (04:37, Vasco)

• On proactive communication:
  "Trying to get tech leads to be the ones to say, oh, I actually identify there is a downstream dependency … just want to let you know this is coming next quarter." (09:19, Renee)

• On using theory of constraints for flow:
  "…control the flow of work into the bottleneck point … so the bottleneck is never overworked … teams get effectively slower than if we would be actively managing their capacity." (10:59, Vasco)

• On experimentation & adapting solutions:
  "The goal … is not to be tied into one single possible solution because then our ego becomes entangled with the solution … but rather to consider many possible solutions because some systems are just complex enough …" (13:14, Vasco)

• On the value of experimentation:
  "I think the experiment approach is definitely one that I use an awful lot as well. Absolutely." (14:11, Renee)

Episode Takeaways

• Downstream teams often become bottlenecks because they’re out of sight during early planning.
• System-wide prioritization and transparent forums for shared services can help align capacity with demand.
• Buffers and proactive communication reduce fire drills and help smooth unpredictable surges of work.
• Consider flow and bottlenecks beyond just the technical—legal or other functions may be crucial choke points.
• Agile teams and organizations benefit from an experimentation mindset; trying multiple solutions iteratively is more effective than clinging to a single approach.
• Balancing risk and workload means sometimes “good enough” work is what’s needed for flow—not perfection every time.

This episode is a goldmine for Scrum Masters seeking practical, systemic strategies to address real-world dependency and bottleneck problems in complex organizations—full of pragmatic advice and the encouragement to experiment rather than over-engineer solutions.
