McKinsey Sustainable Futures Lab guide: overview
The McKinsey Sustainable Futures Lab, usually shortened to SFL, is a scenario-based module within the McKinsey Solve digital assessment. The established version uses environmental research-style context to present judgement decisions rather than test environmental knowledge.
There are now two versions, and each candidate is given one of them: the original 20-minute, 13-question format, and Lab Leader, an approximately 30-minute three-day team-management format that appears in 95-minute invitations. This page covers the original in depth; the Lab Leader guide covers the other.
- Original format
- 20 minutes and 13 sequential questions, in 85-minute invitations
- Lab Leader
- Approximately 30 minutes across three simulated days, in 95-minute invitations
- Core skills
- Prioritisation, working with ambiguity, and stakeholder-aware judgement
- Main challenge
- Keeping decision criteria consistent as information and trade-offs evolve
- Simulator coverage
- Both formats: five original missions and five Lab Leader missions
How SFL differs from Redrock and Sea Wolf
Redrock and Sea Wolf emphasise quantitative analysis and constraint logic. SFL is closer to a situational judgement exercise: prompts reveal information progressively, decisions may influence later options, and trade-offs involve impact, feasibility, timing, and people.
| Module | Focus | Nature | Skills emphasised |
|---|---|---|---|
| Redrock | Data and reporting | Quantitative case study | Numerical reasoning and evidence selection |
| Sea Wolf | Treatment constraints | Rule-based optimisation | Logic, arithmetic, and pattern recognition |
| SFL | Judgement and priorities | Behavioural scenario | Ambiguity, trade-offs, and stakeholders |
What makes the experience different
- Later choices can depend on earlier decisions rather than resetting after each question.
- Information appears progressively, so interpretation matters more than calculation.
- Many prompts have no obviously perfect answer; priorities compete.
- Team dynamics and stakeholder implications can be part of the decision context.
The complete McKinsey Solve guide explains where SFL sits beside the other modules.
McKinsey Sustainable Futures Lab formats and walkthrough
Your invitation and on-screen instructions are the source of truth. The duration tells you which of the two versions you will see.
65 min
Redrock + Sea Wolf
Commonly reported without SFL.
85 min
Original SFL
The 20-minute, 13-question format on this page.
95 min
Lab Leader
The approximately 30-minute three-day format.
Original format: 20 minutes and 13 questions
- Mission briefingRead the team, project, constraints, and priorities carefully; this context carries into later questions.
- Opening rankingDrag and drop objectives or actions into priority order using criteria such as impact, feasibility, risk, and stakeholder alignment.
- Later decisionsMove through 12 multiple-choice questions as the scenario evolves and new information appears.
Earlier choices can shape later context. The key operational challenge is maintaining a coherent decision framework rather than trying to discover one hidden perfect answer.
Lab Leader: the 95-minute format
Lab Leader is a team-management simulation with four Researchers and four Workstations. It runs across Day 1, Day 2, and Day 3, with Notes, placements, and team signals carrying forward. Each day runs the same four stages.
- ExploreSpend a small number of Explore Requests on the available Researchers and Workstations. Everything is saved to Notes.
- AssignPlace each Researcher at a Workstation. The board is shuffled every morning, so this is an active decision each day.
- SupportRespond to four escalations, none of which has a clean answer.
- ReflectRate how each Researcher is finding the work, based on what they told you.
What remains unknown: McKinsey has not published how any of these stages contribute to scoring. The simulator uses its own practice traits for feedback, and does not claim to reproduce McKinsey’s weighting.
The Lab Leader guide walks through each stage, what it tests, and how to practise it. The detailed 95-minute Sustainable Futures Lab report has the original candidate accounts.
Three practice traits for Sustainable Futures Lab
McKinsey does not publish an official SFL scoring rubric. Solve Games Guide uses these three traits as a shared language for reviewing practice decisions; they are not claims about McKinsey’s internal labels.
Working with ambiguity
Move forward responsibly when information is incomplete or changing, balancing action with adaptability.
Teamwork and stakeholder management
Notice inclusion, friction, alignment, and how decisions land with the people affected.
Sustainable Futures Lab strategies and best practices
Separate what the prompt states from the criteria you use to decide. Clear, consistent judgement is more useful than memorising a rigid framework.
Anchor every choice in the briefing
- Identify the stated timeline, budget, quality, and stakeholder constraints.
- On ranking questions, name two or three criteria before moving items.
- Change direction when new information warrants it, not because an option merely sounds more polished.
Maintain a consistent decision framework
Compare options using impact, feasibility, risk, and reversibility. Earlier decisions provide context, but new evidence can justify a thoughtful update.
Use a consulting-team mindset
- Balance progress with quality rather than choosing an extreme by default.
- Consider whose input is missing and how a decision affects delivery.
- Avoid searching indefinitely for a hidden optimal path when the prompt asks for judgement under uncertainty.
How to prepare for McKinsey Sustainable Futures Lab
Most candidates find SFL more intuitive than Redrock or Sea Wolf. Give it enough practice to make the workflow familiar without displacing preparation for the more specialised quantitative modules.
Confirm your likely format
Read the duration and instructions in your invitation. Use the 65/85/95-minute patterns only as preparation guidance.
Learn the established flow
Understand the mission briefing, opening ranking, and interconnected multiple-choice decisions before starting a timed run.
Complete one full timed scenario
Practise the 20-minute, 13-question format in one sitting, then review the criteria behind your choices rather than only the result.
Supplement only where needed
Use broader SJT-style practice for ambiguity and stakeholders. If your invitation states 95 minutes, switch to the Lab Leader guide and practise that format instead.
What not to do
- Memorise rigid frameworks that ignore the scenario.
- Over-prepare SFL at the expense of Redrock and Sea Wolf.
- Study environmental science; the setting supplies context, not a knowledge test.
What is known about SFL scoring?
McKinsey does not publish how either SFL format is scored. There is no verified public answer key, score calculator, weighting model, or evidence that one team allocation is universally optimal.
Useful dimensions for reviewing your own practice
- Consistency across interconnected decisions.
- Fit between priorities and the stated constraints.
- Balance between competing objectives.
- Quality and clarity of the trade-off analysis.
Current limitations
As of September 2026, McKinsey has not published scoring for either SFL format, and there is no verified score-correlation data to share. The simulator’s trait feedback is a practice model, not a reconstruction of McKinsey’s rubric.
In summary: check your invitation duration, practise the matching format, and always follow the instructions you actually receive. For 95-minute invitations, start with the Lab Leader guide.
Practise McKinsey Sustainable Futures Lab
The simulator covers both versions. Original-format missions give you the complete 20-minute, 13-question run: mission context, opening ranking, evolving choices, and trait-aligned feedback. Lab Leader missions give you the full three-day loop with four Researchers and four Workstations, a Practice mode with a pause button, and a review of every placement and Support decision. See the Lab Leader guide for that format.

McKinsey Sustainable Futures Lab FAQ
Answers about the reported formats, invitation timing, preparation, and current practice coverage.
What is the McKinsey Sustainable Futures Lab?
The Sustainable Futures Lab (SFL) is a judgement module in the McKinsey Solve Game. It now has two versions: the original 20-minute, 13-question format, and Lab Leader, an approximately 30-minute three-day team-management format that appears in 95-minute invitations. Each candidate receives one version.
How do I know if I will see SFL in my assessment?
Check the total time in your invitation email. Candidate reports associate 65 minutes with Redrock and Sea Wolf only, 85 minutes with the original 20-minute SFL, and 95 minutes with the approximately 30-minute Lab Leader format.
Does everyone get the same Sustainable Futures Lab format?
No. There are two versions and each candidate is given one of them. The invitation duration tells you which: 85 minutes for the original format, 95 minutes for Lab Leader. Follow your invitation and on-screen instructions.
Is SFL the same as a situational judgement test?
It shares characteristics with situational judgement tests but is not identical. Both reported SFL formats involve decisions under uncertainty, prioritisation, and stakeholder considerations, but their interfaces and workflows differ.
How difficult is SFL compared with Redrock and Sea Wolf?
Most candidates report SFL as the most intuitive of the three modules. It does not require the numerical fluency of Redrock or the constraint logic of Sea Wolf. Maintaining consistent criteria across interconnected decisions is its own challenge.
How should I prepare for SFL?
Practise the version your invitation points to. The simulator covers both: the original 20-minute, 13-question format and five Lab Leader missions with the full three-day loop. If your invitation states 95 minutes, start with the Lab Leader guide.
Can I practice McKinsey Sustainable Futures Lab for free?
McKinsey does not publish a practice version. Solve Games Guide includes one free scenario for the original 20-minute, 13-question format, with no credit card required. Lab Leader missions are included in the paid tiers.
