Planning poker is an effective tool that helps software development teams in Vietnam manage a project in a better way and provide accurate work estimates. How to use planning poker to achieve maximum efficiency? First, let’s understand how planning poker is used. This is an anonymous method, where members of the team together estimate the amount of work for specific features or tasks. To start, each person has a deck with cards with numbers that represent the level of complexity of the task, e.g., Fibonacci or any integer numbers. The use of planning poker usually begins with a discussion of the task to be estimated. Then each member picks a card suitable for his or her opinion and simultaneously reveals the result. If there is a significant discrepancy, the group is discussing again to clarify the influencing factors and come to a final agreement. During the use of planning poker, it is important to create an open-shared environment where all the opinions are heard. Planning poker is also an ideal method for teams distributed remotely using online tools like Jira or Trello. In conclusion, the correct use of planning poker helps the project team in Vietnam to provide accurate work estimates, minimize risk, and increase productivity. This is a flexible estimation method suitable for a wide range of projects.
