overall strategy and analytical approach that you have chosen in order to integrate, in a coherent and logical way, the different components of the study, thus ensuring that the research problem will be thoroughly investigated.
I would first suggest exploring the sustainable materials that can be used for making products and what process is most sustainable for producing those products/forms.
What usage of the pots do you wish to address? Whether it is aimed at residential use or commercial uses.
Living art is another construct that needs to be explored. is it the end product of the plants and pots together that produces a live and dynamic installation or the concept of 'live' is limited to the organic plant entity?
Once there is substantial knowledge and clarity about the methods and constructs and the domain whether residential or commercial, the next step of designing a questionnaire for the residential/commercial users can be drafted. Which is followed by some ideation and conceptual design activity.
