Final answer:
The answer to the project portfolio question is 'incremental', as these projects make only minor modifications or enhancements to existing products or processes.
Step-by-step explanation:
In a project portfolio, incremental projects have objectives or deliverables that are only incrementally different in both product and process from existing offerings. Projects that are described as incremental involve minor modifications or enhancements to an existing product or process.
On the contrary, other types of projects such as transformational, disruptive, or innovative may represent more radical changes or developments that significantly alter industries or markets, as seen with the impact of digital photography on film-based cameras.
These projects involve modifying or enhancing an existing product or process to improve it. Incremental design means that an existing product or process is modified or enhanced to create improvements. This type of project is characterized by making small, iterative changes rather than radical transformations.
Therefore, the correct answer is b) Incremental.
