Remember to always use P-E-E: http://folksonomy.co/?permalink=4192 So, I would change this paragraph to:
Using bricolage provides a more flexible approach to production, which is divorced from the linear requirements. In doing so, it allows me to create tentative experiments, which in being free of the constraints of an overarching purpose - allowed me to try out options according to their best fit according to the changing circumstances of the project. As Matt Rogers explains, bricolage "can be considered a critical, multi-perspectival, multi-theoretical and multi-methodological approach to inquiry" (2012). In the context of my project, this has meant that the process has allowed me to consider all aspects of the project simultaneously - something, which is generally not possible using conventional filmmaking methods.
Also, note that 'centring' is the British English spelling of your (American English) "centering"
