Overview

Scenario 2 – Maintenance Team asks you to design a way of working for a team whose demand you cannot plan far ahead. Maintenance teams fix defects, handle small changes and respond to production issues on products already in use. Work arrives continuously and unevenly, items are usually small, and some are urgent enough that waiting for the next iteration would be unacceptable. Those features point toward DA's Lean lifecycle: work pulled from a visible queue within work-in-progress limits, with planning and replenishment held on a regular cadence rather than tied to fixed iterations.

Candidates must understand how to make such a system predictable without forcing it into time-boxes: explicit policies for intake and triage, classes of service for different urgencies, service level expectations based on measured cycle time, and swarming on blockers. The module also asks you to contrast this design with the enhancement team in module 5 and other team types, which is where the context counts principle is tested most directly.

How it's tested

Questions on this module describe a team with unpredictable, often urgent work and ask for the most appropriate lifecycle, policy or response. Expect contrasts with an enhancement or new-product team. The right answer handles urgency without chaos: visible flow, WIP limits, explicit classes of service and expectations based on measured data, not iterations imposed on work that cannot wait.

  • Choose the lifecycle

    Demand is unpredictable and items are small, and you choose a flow-based Lean lifecycle over an iteration-based one.

  • Handle the urgent item

    A critical production defect arrives, and you choose the response defined by an expedite class of service rather than breaking all limits.

  • Contrast the teams

    Two teams are described and you explain why their best WoWs differ, tying each to its context.

Reasoning it through

A maintenance team runs two-week sprints but abandons its plan most weeks because urgent defects arrive. Ask what the work is like: small, unpredictable and sometimes urgent. Iterations add delay and constant re-planning. The better fit is the Lean lifecycle with WIP limits, an expedite class of service capped at one item, and a regular replenishment meeting. Keeping sprints and simply adding buffer capacity treats the symptom, not the mismatch.

Module topics 2

Official module topics from the PMI outline, in outline order.

6.1 Designing a context-appropriate way of working for a maintenance teamA flow-based design for unpredictable, often urgent work.
What it means
The team designs a WoW that matches continuous, uneven demand: typically the Lean lifecycle with a visible board, WIP limits, explicit intake and triage policies, classes of service and a regular replenishment cadence.
What to understand
Predictability comes from measuring flow, not from fixing scope per iteration. Use cycle-time data to set service level expectations, such as most standard items finished within five working days, and cap expedited work so urgent items do not swamp everything else.
How it shows up
A scenario describes maintenance demand and asks for the most appropriate lifecycle, policy or way to set stakeholder expectations.
Common confusion
Believing flow-based means no planning; Lean teams still hold regular replenishment, review and retrospective sessions, just not tied to iterations.
6.2 Contrasting maintenance with other team needsWhy the same organization needs different WoWs.
What it means
The module compares the maintenance team with teams such as the enhancement team, whose planned feature work suits iterations, and new-product teams, whose uncertainty may suit the Exploratory lifecycle first.
What to understand
Differences in demand pattern, urgency, item size and uncertainty drive different lifecycle and practice choices, while shared governance and milestones keep the organization coherent. A team that both enhances and maintains may need explicit capacity allocation or separate classes of service.
How it shows up
Two teams in the same organization are described, and you identify which context factor justifies their different WoWs.
Common confusion
Thinking different WoWs across teams means inconsistent governance; DA governs outcomes and milestones, not identical practices.

High-yield concepts

The terms, rules and formulas this domain turns into questions most often.

  • Maintenance team

    A team that keeps a product in use healthy by fixing defects, handling small changes and responding to production issues, with demand that arrives continuously and unpredictably.

    Remember
    Small, uneven, sometimes urgent work is the defining context.
    Tested as
    Recognizing this context is the first step in every question in the module.
    Trap
    Applying an iteration cadence designed for planned feature work.
  • Lean lifecycle

    DA's Kanban-based lifecycle in which work is pulled from a queue as capacity frees up, within WIP limits, with meetings held on their own cadence rather than per iteration.

    Remember
    No iterations, but still disciplined: explicit policies, regular replenishment and continuous improvement.
    Tested as
    Usually the most appropriate starting lifecycle for a maintenance team.
    Trap
    Describing it as unplanned or ad hoc.
  • Classes of service

    Classes of service are policies that treat work types differently by urgency and cost of delay, commonly expedite, fixed date, standard and intangible.

    Remember
    Expedite items jump the queue but are capped, often to one at a time.
    Tested as
    Appears whenever urgent and routine work compete.
    Trap
    Marking many items as expedite, which makes the class meaningless.
  • Expedite lane

    A board lane for genuinely urgent items, such as a production outage, that may exceed normal WIP limits and get immediate attention.

    Remember
    Strict entry criteria and a cap keep it from eroding standard flow.
    Tested as
    The correct way to handle a critical defect in a flow system.
    Trap
    Dropping all WIP limits whenever something urgent arrives.
  • Service level expectation (SLE)

    A forecast based on past cycle times, such as 85% of standard items finished within five working days.

    Remember
    It is derived from measured data and stated as a probability, not a promise for every item.
    Tested as
    Used to set stakeholder expectations without fixed iteration commitments.
    Trap
    Quoting average cycle time as a commitment for every item.
  • Replenishment cadence

    A regular session where the team and stakeholders choose which queued items to pull next, decoupled from delivery timing.

    Remember
    Planning still happens on a rhythm; delivery happens whenever items finish.
    Tested as
    Answers the 'how do Lean teams plan' question.
    Trap
    Thinking work is chosen ad hoc by whoever shouts loudest.
  • Explicit policies

    Written, visible rules for how work enters, moves and leaves the system, such as triage criteria, definitions of done per stage and WIP limits.

    Remember
    Making policies explicit lets the team improve them deliberately.
    Tested as
    Appears when the team argues about which item is next.
    Trap
    Relying on the team lead's judgment each time instead of agreed rules.
  • Swarming

    Team members stop starting new work and collaborate on a blocked or urgent item until it moves.

    Remember
    Swarming applies stop starting, start finishing and shortens cycle time for the blocked item.
    Tested as
    A common correct response to a blocked item in a WIP-limited system.
    Trap
    Pulling a new item to stay busy while something stays blocked.
  • Capacity allocation

    Reserving a share of a team's capacity for each work type, such as planned enhancements versus unplanned maintenance.

    Remember
    Useful for mixed teams so urgent work does not starve planned work, or the reverse.
    Tested as
    Appears when one team handles both enhancement and maintenance.
    Trap
    Letting maintenance silently consume all capacity, then missing feature commitments.

Side by side

Concepts candidates mix up, compared on the point that decides the answer.

Maintenance team vs. enhancement team

ConceptMeaningKey differenceCommon trap
Maintenance team Handles continuous, unpredictable fixes and small requests Flow-based Lean lifecycle with classes of service usually fits Forcing urgent defects to wait for the next iteration
Enhancement team Delivers planned new capability on an existing product Iteration-based Agile lifecycle or continuous delivery often fits Assuming the maintenance team's flow design suits planned feature work equally well

Expedite vs. fixed date vs. standard class of service

ConceptMeaningKey differenceCommon trap
Expedite Urgent work with very high cost of delay, such as an outage Pulled immediately, capped in number Overusing it until everything is urgent
Fixed date Work whose value drops sharply after a known date, such as a regulatory change Scheduled so it finishes before the date Starting it too late because it is not yet urgent
Standard Routine work with steady cost of delay Pulled in order under normal WIP limits Letting it starve behind expedited items

Iteration commitment vs. service level expectation

ConceptMeaningKey differenceCommon trap
Iteration commitment Team forecasts a set of items for a time-box Scope set at planning; fits predictable work Constant breakage when urgent work arrives mid-iteration
Service level expectation Probabilistic forecast of item cycle time from past data Set per item type; fits continuous demand Treating it as a guarantee for every item

Exam traps

Each trap is an answer that looks right. Learn the clue that should change your mind.

  1. Keep sprints, add buffer

    What candidates pick
    Reserving sprint capacity for interruptions while keeping two-week iterations.
    Why it looks right
    It keeps a familiar structure and seems pragmatic.
    Why it's wrong
    When most work is unplanned, the mismatch remains; a flow-based lifecycle fits the demand pattern directly.

    Clue to watch for Most of the team's work arrives unpredictably, not only occasional interruptions.

  2. Drop all limits for urgency

    What candidates pick
    Suspending WIP limits whenever an urgent defect arrives.
    Why it looks right
    Urgent work clearly needs attention now.
    Why it's wrong
    An expedite class with a cap handles urgency without collapsing flow for everything else.

    Clue to watch for Urgent items arrive regularly, not once in a crisis.

  3. Everything is expedite

    What candidates pick
    Letting stakeholders mark their items expedite.
    Why it looks right
    It keeps stakeholders happy.
    Why it's wrong
    If every item is expedite, the class carries no meaning and standard work starves.

    Clue to watch for The expedite lane is always full.

  4. Promise every item by a date

    What candidates pick
    Committing to finish each request within the average cycle time.
    Why it looks right
    A firm promise sounds reassuring.
    Why it's wrong
    Half of items exceed the average; an SLE stated as a probability from measured data sets honest expectations.

    Clue to watch for Stakeholders ask how long a typical request will take.

  5. One WoW for consistency

    What candidates pick
    Making the maintenance team adopt the enhancement team's iterations.
    Why it looks right
    Uniform processes look easier to manage.
    Why it's wrong
    Context counts; DA keeps governance consistent through outcomes and milestones, not identical practices.

    Clue to watch for The two teams' demand patterns are described differently.

  6. Stay busy on new items

    What candidates pick
    Pulling new work while an item is blocked.
    Why it looks right
    Nobody sits idle.
    Why it's wrong
    It raises WIP and cycle time; swarming on the blocker is the flow-friendly response.

    Clue to watch for An item has been blocked for days while new work starts.

Answer framework

Use this sequence when a question asks how to design or fix a maintenance team's way of working.

  1. Describe the demand pattern: arrival rate, predictability, typical item size and how often items are genuinely urgent.
  2. If demand is continuous and unpredictable, start from the Lean lifecycle with a visible board, explicit policies and WIP limits.
  3. Define classes of service with explicit entry criteria, capping expedite work so standard and fixed-date work keeps flowing.
  4. Measure cycle time, set service level expectations as probabilities, and hold regular replenishment sessions with stakeholders to choose what comes next.
  5. Contrast the design with other teams' contexts, keep governance consistent through shared outcomes and milestones, and improve policies such as WIP limits and triage rules through measured experiments.

Study strategy

Begin by describing the maintenance context in your own words: small, uneven, sometimes urgent work on a product people rely on. Then learn the Lean lifecycle as the answer to that context, focusing on what replaces iteration planning: replenishment, WIP limits, explicit policies and service level expectations.

Next, study classes of service carefully, since most urgency questions turn on them. For each class, write one realistic example from a maintenance team and the policy that governs it. Practise setting a service level expectation from a small set of cycle times so the idea of a probabilistic forecast feels concrete.

Commonly underestimated areas are the contrast with other teams, which carries many of the scenario questions, and the discipline of a flow system, which candidates often mistake for no process at all. Afterwards, place your module 5 improvement plan beside a maintenance team plan and list every difference with its context reason. Then move to Exploring More Scenarios, which extends this contrast to complex delivery and non-IT teams.

FAQ

Must a maintenance team use the Lean lifecycle?

No. DA does not mandate it, but continuous, unpredictable demand usually fits a flow-based lifecycle better than fixed iterations. Context decides.

How does a Lean team plan without sprints?

It holds regular replenishment sessions to choose what to pull next, reviews and retrospectives on their own cadence, and uses measured cycle times to forecast.

How should urgent production issues be handled?

Through an expedite class of service with clear entry criteria and a cap, so urgent work starts immediately without collapsing normal flow.

What is a service level expectation?

A forecast from past data, such as 85% of standard items finished within five working days. It sets honest expectations without promising a date for every item.

What if a team does both enhancement and maintenance?

Make both work types visible, use capacity allocation or separate classes of service, and measure each so neither silently consumes the other.

Does using different WoWs across teams break governance?

No. DA keeps governance consistent through shared outcomes, milestones and guardrails while letting each team choose practices suited to its context.

How long should I spend on this module?

Plan for about two to three hours, including writing classes of service and comparing your design with the enhancement team scenario.
