== Meaning and Importance of Cohesion ==

Nowadays project teams are largely employed in many different industries, in change management projects within organisations and in education as well. The major advantages of teams are the diversity in knowledge and ideas and, if the team is in good sync, the ability to be more effective and efficient than a single person. Psychological aspects have been identified as key elements of project success and efficacy, in particular, it exists a positive correlation between team cohesion and team performance. <ref name="first"/> Cohesion fosters motivation among team-mates and allows coordination, increases creativity and allows a more freely exchange of knowledge and expertise. <ref name="third">Shmuel Stashevsky and Meni Koslowsky Bar-Ilan.

According to the Merriam-Webster dictionary, cohesion is “the act or state of sticking together tightly”.

At first, team cohesion researchers presented cohesion as a unidimensional characteristic of high-performing teams referring to it as “a field of forces making group members stay together”. <ref name="first"/> The unidimensional description was too vague to convert it in a measurable characteristic, therefore a new multidimensional description was adopted. The most common one is tridimensional and includes:
 
•	“'''Social cohesion'''” that refers to interpersonal attraction between team-mates, interest in other’s company, time spent together and friendship or closeness;

•	“'''Task cohesion'''” that reflects the shared commitment of a team to a certain task or goal and the motivation to coordinate team efforts to achieve goals;

•	“'''Group pride'''”, a dimension studied mostly in sport teams.<ref name="first"/>

Since it takes time to create meaningful bonds, one of the most relevant factors that influences cohesion is the time spent together.
