This article aims to provide a comparative study between theater and performance art, focusing on a particular approach to design and execution in theater. In this approach, everything happens collaboratively, and instead of individual directing and playwriting, design and execution are carried out as a group effort, with the author primarily guiding and directing the group. This method has been employed in several plays by Wajdi Mouawad, a French-Lebanese playwright, actor, and director. Using a close reading of the play "Incendies" by Wajdi Mouawad as a case study, this article examines this distinct style of design and performance in theater. Additionally, it delves into the qualitative aspect of time, considering the element of time within this play from the perspective of Gilles Deleuze.
