Model‐Based Project‐Product Lifecycle Management and Gantt Chart Models: A Comparative Study
Systems Engineering, 2017Co-Authors: Amira Sharon, Dov DoriAbstract:Systems engineering (SE) and project management (PM) are two complementary disciplines that aim at achieving a common goal. In order for systems engineers and project managers to communicate efficiently, there is a need for a common language that balances system performance, quality, stakeholder expectations and needs, cost, and schedule. We use Object Process Methodology (OPM) as the basis for Project-Product Lifecycle Management (PPLM), where SE and PM are complementary parts of an overarching system. Since the project plan is one of the first artifacts that both SE and PM professionals should agree on, we compared Gantt Chart, a commonly used method, and a PPLM project plan. We present a three-stage comparative research, investigating how differences between a Gantt Chart and an OPM model-based PPLM project plan are perceived by mid-career systems engineers, who were graduate students in systems engineering academic programs. The outcomes indicate that the comprehension of information contained in the OPM model-based PPLM project plan is more easily grasped than the same information presented via the Gantt Chart. The results suggest that PPLM has the potential to better clarify the intricate relationships between SE and PM involved in developing systems through projects. It can enable better understanding and communication between systems engineers and project managers, thereby improving decision-making, project outcomes, and product performance.

Beyond the Gantt Chart: - Project management moving on
European Management Journal, 2001Co-Authors: Harvey MaylorAbstract:Large-scale engineering projects have traditionally dominated the subject of project management. Today, however, project management has become a core business process for most organisations. This paper argues that the academic subject and many of the practices have lagged this change. Particular problems are identified with the role of strategy and planning, the units of assessment, the planning process itself and the body of knowledge of the subject. An alternative view of project management is proposed based on an integrative model and areas for further development are identified.

An empirical study on the effect of 3D visualization for project tasks and resources
Journal of Systems and Software, 2016Co-Authors: Khaled Jaber, Bonita Sharif, Chang LiuAbstract:Project tasks and resources were visualized in three-dimensional graphics.A controlled study confirmed effective support for project management.This approach led to 40% higher accuracy and 39% less time. During software development, project managers (PMs) continually monitor, analyze and control the project schedule. The schedule contains tasks, work items, and resources assigned to carry out the tasks. Current state-of-the-art monitoring involves methods such as Gantt Charts and spreadsheets/tables to display and analyze the project schedule, tasks and resources information PMBOK (2004). These methods, however, have certain limitations. It is difficult to see the entire schedule in a single view and analyze the tasks and resources especially in the case of large data. There is also little support for interacting with the data, and the Gantt Chart does not show history information and trends. In this paper, we develop an approach that uses 3D visualizations to represent information about project tasks and resources, to overcome the above limitations. To assess our approach, we conduct an empirical study on real-world projects using 42 participants from both academia and industry. We developed a prototype tool named 3DProjView for the study. The study compared the effectiveness and efficiency of using 3D visualizations versus Gantt Chart and tables. The results indicate that participants using 3D visualizations achieved an average of 40% higher accuracy and spent on average 39% less time analyzing project tasks and resources, further indicating that our approach effectively helps project managers in both accuracy and efficiency for monitoring project performance.

Integration of Program Evaluation and Review Technique (PERT), Gantt Chart and Genetic Algortihm
2014Co-Authors: Siti Hasziani AhmadAbstract:Project scheduling is important to the completion of a project. Since having delay, out of inventory and budget overrun make the failure of the project, project managers shall be able to handle a project with a certain scheduling decision making tool accordingly. A good technique for scheduling the project is required such that a proper manageable schedule can be suggested. In this thesis, the discussion on the integration approach, which combines Program Evaluation and Review Technique (PERT), Gantt Chart (GC) and Genetic Algorithm (GA), is carried out. However, there are another techniques that have been considered before choosing that techniques which are Critical Path Method (CPM) and Work Breakdown Structure (WBS). The aims are (1) to review the existing scheduling techniques, (2) to propose an integrated approach for solving the scheduling problem in the construction industry, and (3) to compare the applicable of the approach proposed with the existing techniques. For doing so, three steps are taken into account. First, doing the integration of PERT and GC, where Earliest Start time (ES) and Earliest Finish time (EF) are calculated. Second, is applying GA to the existing integration approach. In GA procedure, the chromosome is generated randomly to obtain the gene of parents. Further from this, the gene of offspring is refined through the operators of crossover and mutation. Third, the diagram of GC is depicted. For illustration, a set of the real data obtained from a construction company is studied. The project is to build the bounding walls at four different roads in Pasir Gudang, Johor Bharu. By using the approach proposed, a comprehensive schedule is produced, where the finishing time of the project is six day earlier or 6.06% than the original finishing time, which is 99 days. In conclusion, the efficiency of the approach proposed is highly recommended for project managers in developing an effective schedule.

Project management scheduling through integrated PERT and Gantt Chart
2013Co-Authors: Siti Hasziani Ahmad, Abdul Talib Bon, Raja Zuraidah Raja Mohd Rasi, Kek Sie-longAbstract:In project management, scheduling is one of the important activities, where the project can be successfully finished within a desired time period. This study reviews the existing techniques in solving the scheduling problems. An integration technique between Program Evaluation and Review Technique (PERT), and Gantt Chart is proposed for a better scheduling such that the efficiency of the proposed approach and the existing techniques can be compared. Data collection was carried out and the previous monthly data of the production was taken. After collecting data, the data will be transformed into PERT diagram and then the duration time and cost of the production were calculated. Consequently, the Gantt Chart of the production was developed. As a result, an optimal scheduling can be suggested in future.
