The concept of gathering feedback through incremental delivery and regular demonstrations is a quintessential part of Agile methodologies, and features prominently in the PMI Agile Certified Practitioner (PMI-ACP) exam. The idea behind this practice is to develop a product iteratively, delivering working components to stakeholders frequently, thereby facilitating timely feedback and allowing for continuous improvement.
Fundamental Principles
Incremental delivery is the process of developing the product in small, manageable parts, allowing for frequent and meaningful demonstrations. The main objectives are quicker validation of functionality, rapid feedback, and immediate rectification of any inconsistencies. It adheres to the Agile principles of valuing customer collaboration and responding to change over adhering to a rigid plan.
Frequent demonstrations, usually in the form of sprint reviews or product demos, are another crucial component of Agile methodologies. These demonstrations, which typically take place at the end of each iteration or sprint, provide an opportunity for the team to showcase their work. They serve as a platform for obtaining stakeholder feedback and input, aligning with the iterative nature of Agile.
Adding Value to the Product
Taking the specific example of Scrum, a popular Agile framework, the product owner, development team, and stakeholders come together at the end of every sprint for a sprint review. Here, the team presents its increment, i.e., potentially shippable product increment (PSI), emphasizing new features and enhancements. The stakeholders are thus able to see the work in progress, provide inputs and even change their requirements based on the PSI. This ensures that the product is being built not just as per the initial plan, but is continuously molded as per evolving customer needs, leading to higher customer satisfaction.
Similarly, in Lean Production, another Agile framework, the team works based on a pull system, where every new work item is a response to a customer need. This, coupled with the transparency and communication afforded by continuous integrations, makes for a product that is in tune with user requirements at all times.
Combining the feedback received, the team can refine and prioritize the backlog, planning for improvements in the subsequent sprints. The ability to adapt and improve based on feedback received is a key strength of Agile.
Some Considerations
While this principle is largely beneficial, care needs to be taken when collecting and incorporating feedback. It is common to receive feedback from many stakeholders with varying perspectives. It is crucial to strike a balance and consider what actually brings value to the product and aligns with the product vision and strategy.
The table below illustrates the contrasts between the traditional approach and the Agile approach in this context:
| Traditional Approach | Agile Approach | |
|---|---|---|
| Feedback | Collected at project delivery | Collected continuously throughout product development |
| Response to Change | Limited due to rigid plans and contracts | Encouraged and incorporated in between sprints |
| Product Value | Based on initial requirements, may not cater to evolving customer needs | Enhanced continuously based on stakeholder feedback |
In conclusion, the practice of seeking feedback through incremental delivery and regular demonstrations helps in keeping the product in line with customer needs, thus adding value. It also facilitates better stakeholder engagement and higher product quality. While the PMI-ACP exam encompasses a wide array of knowledge areas, familiarity with this principle is a definite advantage.

What outcomes can frequent demonstration lead to in Agile?
- A. User disinterest
- B. Overlooking of minor product issues
- C. Improvement in product based on feedback
- D. Decreased customer interaction
Answer: C
Explanation: Frequent demonstration forms the basis for customer feedback, which can then be used to improve the product.
Single Select: Which of the following is a benefit to frequent demonstrations?
- A. Decreased customer engagement
- B. Delayed product delivery
- C. Increased development costs
- D. Timely feedback and improvements
Answer: D
Explanation: Frequent demonstrations help in gaining timely feedback and making improvements, thereby enhancing the product performance and value.
True or False: Demonstrations after incremental delivery can lead to effective stakeholder engagement.
- True
- False
Answer: True
Explanation: Regular demonstrations provide stakeholders with an opportunity to provide feedback and participate in product improvements, leading to their active involvement and engagement.
Multiple Select: Seeking feedback through incremental delivery, organizations can benefit from,
- A. Early problem detection
- B. Enhanced customer satisfaction
- C. Reduced testing time
- D. Increased development errors
Answer: A, B, and C
Explanation: Incremental delivery not only helps in early problem detection but also enhances customer satisfaction by involving them in the improvement process. It also reduces testing time as the feedback is obtained and acted upon in each increment.
Single Select: Which Agile principle emphasizes on frequent delivery of working software?
- A. Simplicity
- B. Flexibility
- C. Incremental delivery
- D. Continuous improvement
Answer: C
Explanation: The principle of incremental delivery focuses on delivering working software frequently, providing an opportunity for regular feedback and improvements.

- A. Customers or Clients
- B. Focus groups
- C. Development team
- D. All of the above
Answer: D
Explanation: Feedback can be valuable from multiple stakeholders, including customers or clients, focus groups, and the development team. This diverse feedback can significantly contribute to product improvement.
Interview Questions
What does incremental delivery mean in an Agile project?
Incremental delivery in an Agile project refers to the process of delivering a product in small, manageable units or increments, allowing for feedback and improvements with each delivery.
Why is frequent demonstrations elemental in Agile product management?
Frequent demonstrations provide stakeholders with visual proof of progress and allow them to give immediate feedback, thus enabling the project team to adapt to changes quickly and improve the product value.
How does incremental delivery and demonstrations enhance the value of a product?
Incremental delivery allows feedback to be gathered and implemented at regular intervals, allowing for continuous improvement. The product is tweaked and enhanced with each delivery, increasing its overall value. Demonstrations allow stakeholders to visualize the progress and make necessary recommendations.
In the PMI-ACP exam, what is the main purpose of obtaining feedback in an Agile project?
The main purpose of obtaining feedback in an Agile project is to continuously improve the product and meet the customer’s needs more effectively, thereby creating a higher quality product and reducing risks.
Does frequent feedback negatively affect the development pace in Agile method?
No, on the contrary, frequent feedback can effectively speed up the development process by identifying necessary changes earlier, reducing the time and resources spent on corrections later in the project.
How does Agile practices such as incremental delivery and frequent demonstrations deal with changes?
Agile practices allow for changes to be accommodated throughout the development process. With incremental delivery and frequent demonstrations, changes can be incorporated at any stage, resulting in a final product that is in line with customer requirements and expectations.
When should feedback be sought during product development in Agile methodology?
Feedback should be sought after each increment is delivered or after every demonstration. This ensures timely identification and rectification of any issues or problems.
How do incremental delivery and frequent demonstrations align with Agile’s principle of adapting to change?
Both practices allow for continuous inspection and adaptation. They provide opportunities to incorporate change and feedback into the product at any stage, ensuring the product meets customer needs and maximizes value.
How can product value be quantified in Agile?
In Agile, product value can be measured by customer satisfaction, level of functionality, usage statistics, and financial metrics like return on investment.
What is one of the key benefits of incremental delivery and frequent demonstrations in Agile?
One of the key benefits of incremental delivery and frequent demonstrations is risk reduction. These practices allow for early detection and rectification of issues, avoiding large-scale problems at later stages of development.
