Team Behaviour Model as a Tool for Determining the Project Development Trajectory

The scientific novelty of the work consists in the fact that a model of the Scrum team's behavior during the project life cycle has been developed, which takes into account the influence of the participants' competence and role potential on the result of team work. Based on the Drexler and Sibbet's team behavior model, the model 7 F's is proposed. This model reflects 7 stages of the project team members working together: Finding, Faith, Focus, Functioning, Forcing, Fruitfulness and Forwarding. This model is presented in the form of a Markov chain, where seven stages of team behavior are presented in the form of a graph of transitions from one state to another, the probabilities of transition to other states, as well as the probabilities of maintaining current states, are indicated. The transition probabilities of the Markov chain for the seven stages of team behavior determine its characteristics that change in discrete time in steps in the form of a certain set of state probabilities. The cognitive property of a model built on the basis of the Markov chain allows you to set certain specific values for the transition probabilities of the system. Practical recommendations are given for determining the values of transition probabilities for different states of the system. It is shown that the probabilities of the transition of system states can be determined on the basis of an estimate of the time spent moving from one stage of joint teamwork to another. Two options for team behavior are being studied, i.e. the basic version of team behavior and team behavior after the implementation of the in-depth knowledge system and the adaptive knowledge generation system. The study shows the change in state probabilities through the implementation of these systems. The proposed model allows quantifying the current progress of the project processes as a result of changes in the project team and time costs caused by problems that each participant and the whole team may encounter at seven stages of teamwork. The 7 F's model is applied at the Retrospective stage in the Scrum process in order to increase the efficiency of the Scrum team within new iterations.
