“…Most of these studies report from one or a few cases of successful application and, on that basis, recommend the presented approach to other small software firms. Examples are DSDM and people process (Coleman and Verbruggen, 1998), AMETIST (Thowart, 1999), TAPESTRY (Kuvaja et al, 1999), 3P approach (Brouse and Buys, 1999), IMPACT (Scott et al, 2001), Software Process Matrix (Richardson, 2001(Richardson, , 2002, MESOPYME (Villalon et al, 2002), COSMEA (Grechenig and Zuser, 2004;Steel, 2004), and SPICE (Truffley et al, 2004). While these studies vary considerably in focus, they all advocate a need for adopting SPI-technology and they propose ways to downsize the effort to better match the resources and culture of small software firms.…”
