The iterative aspect involves repeating cycles of work where each cycle refines and improves upon previous results. Teams revisit requirements, designs, and outputs multiple times, incorporating feedback and lessons learned from each iteration. This allows for continuous improvement and adjustment based on real-world experience and stakeholder input.
The incremental aspect focuses on delivering products or outputs in smaller, manageable portions rather than as one complete package at the end. Each increment provides usable functionality or value, building upon previous increments until the final product is complete. This enables stakeholders to receive benefits earlier in the project lifecycle.
When combined, the iterative-incremental approach offers several advantages. It reduces risk by allowing teams to identify and address issues early through regular review cycles. Stakeholder engagement improves because they can see and evaluate working outputs throughout the project rather than waiting until completion. The approach also accommodates changing requirements more effectively, as adjustments can be incorporated into subsequent iterations and increments.
PRINCE2 7 recognizes that this approach is particularly valuable in environments where requirements may evolve or where early delivery of partial solutions provides business value. It aligns well with agile ways of working while remaining compatible with the structured governance that PRINCE2 provides.
The approach requires careful planning to define appropriate iteration lengths, increment scope, and integration points. Project managers must balance the flexibility of iterative work with the need for overall project control and direction. Success depends on effective communication, regular feedback loops, and a willingness to adapt based on what is learned during each cycle of work.
Iterative-Incremental Approach in PRINCE2
What is the Iterative-Incremental Approach?
The iterative-incremental approach is a fundamental concept in PRINCE2 that combines two complementary delivery methods:
Iterative: This involves repeating cycles of work where outputs are refined and improved through successive passes. Each iteration builds upon feedback and lessons learned from previous cycles.
Incremental: This involves delivering the project's products in small, usable portions rather than waiting until the entire project is complete. Each increment adds functionality or value to what has already been delivered.
Why is it Important?
The iterative-incremental approach is crucial for several reasons:
• Early Value Delivery: Stakeholders receive usable products earlier in the project lifecycle • Reduced Risk: Problems are identified and addressed sooner rather than later • Improved Quality: Regular feedback loops allow for continuous refinement • Better Adaptability: The project can respond to changing requirements and circumstances • Enhanced Stakeholder Engagement: Regular deliveries keep stakeholders involved and informed • Increased Confidence: Progress is demonstrated through tangible outputs
How Does it Work in PRINCE2?
In PRINCE2, the iterative-incremental approach works through:
Stage Planning: Each management stage can include multiple iterations and increments
Work Packages: The Team Manager organizes delivery work into manageable chunks that can be developed iteratively
Product-Based Planning: Products are broken down to allow for incremental delivery
Regular Reviews: Checkpoints and stage assessments provide opportunities to incorporate feedback
Benefits Realization: Early increments enable earlier realization of project benefits
Exam Tips: Answering Questions on Iterative-Incremental Approach
1. Distinguish Between the Two Terms: Remember that iterative relates to refinement through cycles, while incremental relates to partial deliveries of functionality
2. Link to PRINCE2 Principles: Connect this approach to principles like 'continued business justification' and 'learn from experience'
3. Focus on Benefits: Questions often test whether you understand the advantages, particularly around risk reduction and early value delivery
4. Consider Context: The approach is especially valuable when requirements are uncertain or when early feedback is beneficial
5. Remember Flexibility: PRINCE2 allows tailoring of how iterative and incremental the approach should be based on project needs
6. Watch for Scenario Questions: You may be asked which approach suits a particular project situation - look for clues about uncertainty, stakeholder needs, and risk tolerance
7. Avoid Confusion with Agile: While similar concepts exist in Agile, focus on how PRINCE2 applies these concepts within its framework of stages and controls
8. Key Phrases to Remember: 'Successive refinement', 'partial deliveries', 'feedback incorporation', and 'staged value realization'
