The six aspects are: Time, Cost, Quality, Scope, Benefits, and Risk. Traditional project management often treats all these as flexible, but PRINCE2 Agile recommends 'fixing' certain aspects while allowing others to 'flex' to ensure successful delivery. Time and Cost are typically fixed. This means deadlines and budgets are held constant, which suits agile's use of timeboxing and fixed team resources. Fixing time and cost provides predictability and protects the schedule and financial commitments. Quality is also generally fixed, particularly the minimum acceptable quality criteria and standards that must be met. This ensures the product remains fit for purpose and does not degrade under pressure. Scope and, to some extent, the level of detail delivered are the primary aspects that flex. Rather than delivering everything, agile teams prioritize requirements (often using techniques like MoSCoW prioritization) so that the most valuable features are delivered first. Lower priority items may not be delivered if time or cost constraints are reached. This ensures that what is delivered is always the most important work. Benefits should be understood and protected, ensuring that flexing scope does not undermine the core value the project must deliver. Risk is managed continuously and is influenced by decisions made across the other aspects. The 'Fix and Flex' approach allows teams to deliver on time and on budget while maintaining quality, by being flexible about exactly what is delivered. This contrasts with traditional approaches where time and cost often flex when scope is fixed. By fixing time, cost, and quality, and flexing scope, PRINCE2 Agile achieves both agility and control, aligning with the principle of being on time and hitting deadlines reliably.
Fix and Flex: Six Aspects of Performance in PRINCE2 Agile
Introduction The concept of 'Fix and Flex' is one of the most important ideas in PRINCE2 Agile. It explains how the six aspects of project performance (also called the six variables or six tolerance areas) can be managed differently when working in an agile way. Understanding this concept is essential for the PRINCE2 Agile Foundation exam and for applying agile thinking within a controlled project environment.
Why It Is Important In traditional project management, teams often try to fix (control tightly) all aspects of a project at the same time — scope, time, cost and quality. This creates tension and often leads to compromises on quality or missed deadlines. PRINCE2 Agile recognises that this rigid approach conflicts with agile ways of working.
The Fix and Flex approach helps teams protect what matters most — typically time, cost and quality — while allowing scope to flex. This preserves delivery deadlines and budgets, protects the quality of the product, and still delivers value to the customer. It is important because it reduces stress, improves predictability, and ensures the most valuable features are delivered first.
What It Is: The Six Aspects of Performance PRINCE2 identifies six aspects (or performance targets) that must be managed on every project. PRINCE2 Agile adds guidance on which of these should be fixed and which should flex:
1. Time — When the project or release will be delivered. In agile, this is normally fixed. 2. Cost — The budget for the project. This is normally fixed. 3. Quality — Whether the product is fit for purpose. Acceptance criteria and quality standards are normally fixed. 4. Scope — What will be delivered (the features and requirements). This is normally allowed to flex. 5. Benefits — The measurable improvements expected. These should be well understood and are broadly fixed in terms of the reason for the project. 6. Risk — The uncertainty around the project. Risk tolerance is managed and can flex as appropriate.
How It Works The core idea is that time and cost are held firm (fixed), while the scope and quality of detail flex. Rather than delivering everything late or over budget, the team delivers on time and on budget but adjusts what is delivered.
This is enabled by prioritisation techniques such as MoSCoW (Must have, Should have, Could have, Won't have this time). The 'Should have' and 'Could have' requirements provide the flexibility — if time runs short, these can be dropped without breaking the deadline.
A crucial point often tested in exams: quality criteria are fixed, but the level of detail within scope can flex. The product must still meet its acceptance criteria and be fit for purpose — flexing scope does not mean delivering poor quality work. You never sacrifice quality to save time; instead you reduce the number of features delivered.
The 'five targets' idea is sometimes summarised as: be on time and hit deadlines, protect the level of quality, embrace change, keep teams stable, and accept the customer doesn't need everything. This mindset underpins Fix and Flex.
How to Answer Exam Questions Foundation-level questions on this topic are usually multiple choice and test your recall of which aspects are typically fixed and which flex. Focus on the standard mapping: Time, Cost, and Quality are typically fixed; Scope is the primary aspect that flexes.
Be careful with questions that try to trick you into thinking quality can be reduced. In PRINCE2 Agile, you flex scope, not quality. Also remember that flexing scope means using prioritisation (MoSCoW) so that the most important requirements are always delivered.
Exam Tips: Answering Questions on Fix and Flex: Six Aspects of Performance Tip 1: Memorise the six aspects — Time, Cost, Quality, Scope, Benefits, Risk. A common exam question simply asks you to list or identify them.
Tip 2: Remember the key rule: fix time, cost and quality; flex scope. If a question suggests quality should be sacrificed to meet a deadline, it is almost certainly the wrong answer.
Tip 3: Link Fix and Flex to MoSCoW prioritisation. Questions often connect the flexing of scope to how requirements are prioritised.
Tip 4: Watch for the distinction between quality criteria (fixed) and the amount delivered (flexible). This subtle point is frequently tested.
Tip 5: Understand the reasoning, not just the facts. If asked why time and cost are fixed, the answer relates to protecting delivery predictability and enabling regular, valuable delivery.
Tip 6: Read questions carefully for the word 'normally' or 'typically' — PRINCE2 Agile acknowledges these are default positions that can be adjusted based on project circumstances.
Summary Fix and Flex is about protecting what matters most (time, cost, quality) and allowing flexibility where it is safe to do so (scope). By fixing the deadline and budget and flexing the detail of what is delivered, teams achieve predictable delivery while still adapting to change — the heart of the agile mindset within PRINCE2.
