Research Insights

Work Package Sizing and Project Performance
Operations Research, 67(1), 123-142 (2019)

The authors study how design decisions in project planning affect the cost of execution. In organizing a project's tasks into work packages, trade-offs arise. Defining small work packages increases project complexity and workload, and reduces economies of scale, whereas defining large work packages reduces concurrent processing and adversely affects cash flow. Their work is apparently the first to study this trade-off. They consider the objective of minimizing total project cost, subject to a deadline on project makespan. For serial task networks, they describe an efficient algorithm that finds optimal work package sizes. For acyclic task networks, they develop a heuristic method and a lower bound for the unary NP-hard problem. A computational study shows that their heuristic routinely delivers near-optimal solutions that substantially improve on those found by benchmark procedures. The results demonstrate the value of deliberately varying work package sizes within a project, in contrast to typical project management practice. Related issues including multiple serial paths in parallel, task incompatibility, and generalized precedence constrained work packages are also discussed. Their work enables more precise planning of work packages to improve performance, documents the value of integrating the planning of work packages and schedules, and provides insights that guide resource allocation decisions.

The Sleepy Consumer and Variety-seeking

Sleepiness, the subjective feeling of the propensity to fall asleep, is a common, everyday experience that can be induced by various factors, such as sleep quality, sleep deprivation, ingestion of certain substances, or belief about how much sleep a person needs. Despite its prevalence, sleepiness and its influence on consumption behaviour have rarely been linked in the research to date. The present research helps fill this void by uncovering the novel impact of sleepiness on consumer variety-seeking behaviour. The studies, using various methods and all involving consequential choices, revealed that sleepier consumers tended to seek more variety. The driver of this effect was found to be a need for arousal to maintain wakefulness. The authors also show that variety-seeking behaviour is effective in partially reducing sleepiness. The effect of sleepiness on variety seeking uncovered in this research is somewhat non-intuitive, in the sense that, a priori, one might expect sleepiness to be more likely to decrease rather than increase exploratory behaviour. The authors discuss implications of the findings for different research areas and for marketing practice.
