ABSTRACT
Even though scholars increasingly pay attention to time in studying groups and teams (Ancona & Chong 1999; Ancona, Goodman, Lawrence & Tushman 2001; Arrow et al. 1995; Arrow, Poole, Henry, Wheelan & Moreland 2004; Harrison, Mohammed, McGrath, Florey & VanderStoep 2003; Ilgen 1999; Kelly & McGrath 1985, 1990, 1991; McGrath & Tschan 2004a; Schriber & Gutek 1987; Waller, Zellmer-Bruhn & Giambattista 2002), research that explicitly takes time-related aspects into account remains sparse, especially regarding longitudinal studies. For example, Harrison and colleagues (2003) observe that of 161 empirical papers on groups and teams published between 1990 and 2001 in three leading applied psychology journals, only 12 percent were longitudinal or panel studies that followed teams over time.
