The first thing that comes to mind when managing a portfolio is one of the last, most important steps during the Closing Phase, which is to log everything you have done and learned so that they can be applied in the strategy of future projects. A portfolio simply refers to one’s collection of previous programs and respective projects in a way that can facilitate the life cycle of a future project (assuming both have relatable elements), thereby making each successive project more efficient in potentially any task involved in the project’s life cycle. Since a portfolio refers to the collection of an individual in their respective field, it is very likely that what was learned in a prior project can be applied to a pending/in-process project. If a team leader has navigated projects in different fields (such as developing cardio stents and manufacturing microchips), it can mean that they have a broad range of skills and can be more versatile in project management. On the other hand, a team leader who has only worked in developing cardio stents won’t necessarily be a jack of all trades, but they can perhaps have more to offer on a stent-based project than a do-it-all. Portfolios are overall very necessary to have and acquire over one’s career simply because they can only serve to assist.
