In my opinion, completing the product life cycle is not that easy in real life.A bunch of people who are
experts in their fields and are working together to complete a project, will have to overcome many minor
issues with in the team to achieve the target. For instance, the PM might not be on the same page with the
the designer of the product and that leads to friction between the two. Then sometimes, the PM can
be an arrogant person who thinks he/she knows everything and undermines the work of his team and is not open to new ideas. Or he creates an unrealistic deadlines for his team members to work on. In all these above mentioned cases, it creates a frustrating environment.
