Abstract—Despite several attempts to accurately predict duration and cost of software projects, initial plans still do not reflect real-life situations. Since commitments with customers are usually decided based on these initial plans, software companies frequently fail to deliver on time and many projects overrun both their budget and time. To improve the quality of initial project plans, we show in this paper the importance of (1) reflecting features’ priorities/risk in task schedules and (2) considering uncertainties related to human factors in plan schedules. To make simulation tasks reflect features’ priority as well as multimodal team allocation, enhanced project schedules (EPS), where remedial actions scenarios (RAS) are added, were introduced. They reflect potential schedule modifications in case of uncertainties and promote a dynamic sequencing of involved tasks rather than the static conventional way of modeling schedules. This paper describes a methodology to introduce EPS models in the development of project plans. Our case study findings show clearly the ability of the EPS model to anticipate delays due to human factors and to predict remedial scenarios to adjust to such delays. By comparing EPS to classical schedules, EPS simulation provides more accurate results with regards to project goals.
