A computer-executed method for allocating resources is described. Data representative of target percentages of time for a plurality of project activities is received where the target percentages add to 100%. For each target percentage of each project activity, data representative of an amount of the target percentage that at least one of a plurality of individuals performs the corresponding project activity is received. Data representative of a plurality of projects is then received. Data representative of availability of the at least one of the plurality of individuals is received and a predicted need of the at least one of the plurality of individuals during the duration of the project is determined. Data representative of an adjustment to the determined predicted need is received and data representative of the adjustment to the determined predicted need is outputted.
