A wiki knowledge base is a tool that allows the project team to store, organize, and share information that is captured throughout the life cycle of a project. A wiki knowledge base is stored in a centralized location that is easily accessible to all stakeholders via a web browser. A wiki knowledge base also provides search functionality that enables the users to find the information they need quickly and easily. A wiki knowledge base can help the project team to document the project requirements, scope, schedule, budget, quality, risks, issues, lessons learned, and best practices.

A wiki knowledge base is different from a secure folder, which is a tool that protects the files and folders from unauthorized access or modification. A secure folder may not be easily accessible to all stakeholders, and may not provide search functionality or collaboration features. A wiki knowledge base is also different from a real-time, multiauthoring editing software, which is a tool that allows the project team to create and edit documents simultaneously and synchronously. A real-time, multiauthoring editing software may not be suitable for storing large amounts of information, and may not provide the same level of organization and structure as a wiki knowledge base. A wiki knowledge base is also different from a digital whiteboard, which is a tool that allows the project team to brainstorm, visualize, and communicate ideas. A digital whiteboard is not designed for storing information, and may not provide the same level of search functionality or security as a wiki knowledge base.

The environmental factor would be impacted the most by requirements for a project to implement an air quality control system at a coal plant. This is because coal combustion produces various air pollutants, such as particulate matter (PM), sulfur dioxide (SO2), nitrogen oxides (NOx), carbon dioxide (CO2), and mercury, that can harm human health and the environment12. An air quality control system can reduce the emissions of these pollutants by using different technologies, such as low NOx burners, flue gas desulfurization, electrostatic precipitators, and carbon capture and storage23. However, these technologies also have environmental impacts, such as water consumption, waste generation, energy consumption, and greenhouse gas emissions4. Therefore, the project manager should consider the environmental factor in terms of the project scope, objectives, constraints, risks, and stakeholders, and evaluate the trade-offs and benefits of different air quality control options5.

A milestone chart is the best chart to use to show major accomplishments for key events, because it displays the important deliverables or outcomes of a project along a timeline12. A milestone chart can provide a high-level overview of the project progress and achievements, without showing the details of each task or activity34. A milestone chart can also help communicate the project status and expectations to the stakeholders, and identify any potential risks or delays that may affect the project completion56. References = CompTIA Project+ Certification Study Guide7, CompTIA Project+ Certification Exam Objectives8, What is a Milestone Chart?1, How to Create a Milestone Chart in Excel in 3 Steps2, Milestone Chart: The Easiest Way to Track Project Milestones3, How to Use Milestones in Project Management4

The critical path is the sequence of tasks that determines the minimum project duration. It is the longest path through the network diagram and has the least amount of slack or float. Based on the provided network diagram, the critical path is A-C-G-K-M, which has the longest total duration when adding up the individual task durations. References = The concept of the critical path is covered in the CompTIA Project+ Certification Study Guide1. For more detailed information on how to calculate and identify the critical path in project management, you can refer to the study guide and other project management resources2.
