Abstract Long term plans and successful implementation of marketing strategy depends on Organisational commitment of employees. If employee attrition is high, long term plans will suffer. The Organisation Commitment of 50 employees of Marketing and sales department in a South India based National FMCG company was calculated using Allen and Meyer Organisational commitment scale. The Affective, Normative and Continuance commitment sores were calculated. The scores are not mutually exclusive, since a person who has high Affective score may also be in organization for some Normative or Continuance reason. The scores of the three constructs overlap. This gives a distorted picture of the true organizational commitment. To overcome the defect, this paper demonstrates innovative use of probability distribution and Mixed distribution to get the probability score of Organisation commitment. The management can thus know the probability of various scores of commitment and take appropriate steps to improve the organization commitment. It is found that the Affective Commitment score follows a Weibull Distribution with α = 30.25, β= 4.12, γ=0. The Normative construct follows Triangular distribution with parameters m =3, a = 2.63, b= 3.53. The Continuance Commitment has Wakeby distribution with distribution parameter α= 0.53078, β= 3.1003, γ= 0.14264, δ= -0.05068, ξ= 3.2123. The probability of Affective commitment between 4 and 5 is 0.67 or 67%. P(X1 < X< X2) =0.67413, probability of employees having a Normative commitment of between 3 and 3.5 is 0.59 or 59%. P(X1 < X< X2) = 0.59081.The probability of Continuance commitment between 3.3 and 4 is 0.84 or 84% P(X1 < X< X2) = 0.84815. The Mixed distribution shows that the probability of high organization commitment is 22.79% [P(4 < X< 5) = 0.227867]. Probability of medium organization commitment score is 77.2%. [P(3 < X<4) = 0.77207]. The management has to take steps to improve the Organisation commitment.
