Design Of Software Determining The Critical Pathway Of A Project Network
Introduction
Project planning is a crucial aspect of any project, and one of the main objectives is to find the critical path, which is a series of activities that have the longest duration in a project. Delays in activities in this path will cause overall project delays. There are various methods for determining critical paths, such as Pert (Evaluation and Review Technique) and CPM (Critical Path Method). This article will discuss Delphi-based software design to implement the CPM method in determining the critical pathway in the project network.
Software Design Steps
To determine the critical path, this software requires input in the form of activity segments and duration of each segment. This software design involves several stages, namely:
1. Problem Analysis
At this stage, an analysis of the problems encountered in determining the critical path, such as data needs, calculation processes, and expected outputs, is conducted. This stage is essential in identifying the requirements of the software and determining the best approach to develop it.
2. Software Design
This stage includes the design of the user's interface, database design to store project data, and algorithms to calculate critical paths. The user interface should be user-friendly and easy to navigate, while the database design should be able to store and manage large amounts of data efficiently.
3. Data Flow Diagram (DAD)
DAD shows the flow of data in the system, starting from the input of project data, the process of calculating the critical pathway, to the output produced. This diagram is essential in visualizing the flow of data and identifying any potential bottlenecks in the system.
4. Algorithm and Flowchart
The algorithm used in this software must be based on the CPM method to calculate the total duration of each activity, determine the critical path, and display the accurate calculation results. Flowcharts will show the program steps visually, so that it is easier to understand.
Delphi-Based Software Advantages
The selection of Delphi programming languages in this software design has several advantages:
Ease of Use
Delphi has a user-friendly interface and is relatively easy to learn, making it easier in the software development process.
High Performance
Delphi is known to have good and efficient performance in managing data and running programs.
Extensive Component Support
Delphi provides a variety of components that can be used to speed up the development process, so that the programmer can focus on program logic.
Compatibility
Delphi is compatible with various platforms, so that the resulting software can be run on various operating systems.
Benefits of Software for Determination of Critical Pathway
The use of this software in determining the critical pathway in the project network has various benefits, including:
Increasing Accuracy and Accuracy
Calculation of critical pathways using software will be more accurate than manual calculations, so as to minimize errors.
Time Efficiency
Critical pathway calculation process can be done quickly and efficiently using software, so that it can save time and energy.
Facilitate Decision Making
The results of critical path calculations can be used as a basis for making decisions, such as scheduling activities, resource allocation, and risk management.
Improve Communication and Collaboration
Data and calculation results integrated in software can be accessed by all parties involved in the project, thereby increasing communication and collaboration.
Conclusion
Software design to determine the critical pathway in the project network using Delphi has great potential to increase efficiency and accuracy in project planning and management. With an easy to understand interface, reliable performance, and broad component support, Delphi is the right choice to develop software that is able to help professionals in managing projects more effectively.
Future Work
Future work can include:
- Improving the user interface: Making the user interface more user-friendly and intuitive.
