Responding to challenging times has demonstrated that solutions can no longer be an either-or choice. During the pandemic as well as current crises, the combination of different ideas and approaches has proven to be the way forward. In daily business, a new openness for rethinking can be observed, in which remote work, the need of sustainable technologies or the work culture is transformed into hybrid ways. For several years now, the increasing use of hybrid methods has also been evident in the context of project and portfolio management.
For a long time, the waterfall methodology was considered the dominant approach to project and portfolio management. However, since the publication of the Agile Manifesto from the angle of software development in 2001, a change in paradigm has slowly been taking place. This paradigm shift was followed by either-or debates, with questions about agile being disorganized or waterfall being too rigid, or even both methods to be incompatible in use. Finally, fueled by the pandemic, we find ourselves in a time in which both methods with their distinct characteristics are now considered to be equally relevant.
