In this paper a culture-centered multilevel software process cycle model (MPCM) is presented. This model interrelates the socio-cultural, scientific/technological and paradigmatological environments. The proposed model is composed of three environments made up of the ecological universe, engineering, management, development and evaluation levels which represent the process cycle, and the lines of “what”, “who” and “how”. MPCM considers cultural, social, organizational and personnel-related issues, normally absent in the traditional software process models. A cultural comprehensive procedure for the realization of the engineering level is developed. The different stages and their products of the Cultural Procedure of the MPCM are represented. This procedure is proposed in order to model the organization, to reveal its culture and to determine the abilities that a person (user or developer) has to reallocate him/her in the software process.
