Abstract: The invention relates to a method for enabling management of at least one opportunity having a maximum opportunity level and to which one or more exploits that realise the opportunity can be applied, the method comprising: (i) determining the total opportunity improvement of all exploits applicable to at least one opportunity assuming that all said exploits are fully applied to realise the opportunity and that all said exploits are independent of each other; (ii) determining the contribution of the or each said exploit to said total opportunity increase; (iii) determining the level of actual opportunity increase from each said exploit taking into account, for each of said exploits, the contribution of the or each exploit to said total opportunity increase, the dependency of the exploit on other exploits applicable to said opportunity, and the degree to which the exploit is applied to realise said opportunity; and, (iv) determining from said levels of actual opportunity increase from each said exploit the tota
