In the context of PMI Agile Certified Practitioner (PMI-ACP) exam, frequent reviews of work products are integral components of Agile methodologies. Agile stresses on continuous improvement and learning, which underlies the importance of regularly reviewing work products.
Regular inspections, reviews, and/or testing of work products allow teams to keep track of progress, detect and correct errors early, discover opportunities for improvement, and encourage both individual and team learning. These practices also foster an environment of collaboration and collective decision-making, while enabling the team to produce high-quality products/services.
II. Conducting Inspections, Reviews and Testing
Inspections, reviews, and/or testing are practices intended to identify and address shortcomings, promote quality, and derive value. They may occur in different forms such as self-inspection, peer review, group review, pair programming, code review, or test-driven development.
For example, one popular method is Pair Programming. It’s an Agile technique where two programmers work together at one workstation. One person, the Driver, writes the code while the other, the Observer, reviews each line of code as it is typed in. This reduces the defect density in the code and promotes higher quality.
Another example is Test-Driven Development (TDD). In TDD, tests are written before the code itself. These tests define the desired behavior or functionality, and code is then written to pass the tests. It enhances the design, reduces bugs, and improves reliability.
III. Incorporating Improvements into the Overall Process and Product/Service
Catching missteps or identifying possible enhancements during the course of a project provides a chance to make immediate alterations, saving time and money. Agile teams incorporate the lessons learned into the next iteration of development, continually evolving and refining their process and product/service.
For instance, take an ecommerce platform as an example. Through frequent testing of the user interface and functionality, the development team might notice that the checkout process is too lengthy and resulting in high bounce rates. They can adjust the process immediately to make it more streamlined and revisit this change in their next review to observe any improvements.
IV. Benefits Comparison Table
| Traditional Approaches | Agile Approaches |
|---|---|
| Defects are costly as they are found later in the development cycle | Defects are found and corrected early, reducing costs |
| Changes are difficult to make as they require considerable rework or revision | Changes can be implemented easily and quickly |
| Individuals work in silos, resulting in lack of collaboration and learning | Encourages collaboration and collective learning |
| Product/service is tested only towards the end | Product/service is tested at multiple stages and improvements are iterative |
In conclusion, the PMI-ACP emphasizes the foundational principle of Agile methodologies – continual improvement and learning. Frequent reviews, inspections, and testing not only improve the quality of the product/service but also enhance the productivity and efficiency of the team.
