Feasibility of using the gantt chart for the development of project documentation

Abstract

Gantt chart - considered an important part of project management, using the dates on the chart, you can accurately plan the delivery of materials, equipment, work of crews and subcontractors. The top level of the WBS is a project that represents the totality of the entire scope of work. The project consists of smaller works of different scope and importance, which are usually called work packages. The head of works often distributes work packages according to responsibility, assigning a responsible person to each package - an individual, a department, a subcontractor. In turn, each work package is subdivided into tasks or contains its own, smaller, internal work packages, the completion of which marks the end of work on the work package as a whole. Work on a work package is considered completed when the persons responsible for it (team) have completed all internal work packages and all tasks (events). A network diagram allows you to graphically establish the relationship between individual operations/work packages throughout the project area. The relationship and sequence between operations may vary from project to project, depending on the system you use in your work, the availability of funds, employees, etc. Actions are usually planned in a sequential order. Depending on the relationship between the beginning/end of previous and subsequent operations, four types of dependence are distinguished: finish-start – a new operation begins immediately after the end of the previous one; start-start – the start of the next operation is related to the start of the previous one, that is, in fact, two operations start at the same time; finish-finish - the finish of the next one depends on and is connected with the end of the next one, that is, two operations are completed simultaneously; start-finish – the beginning of the previous operation is connected with the end of the next one, that is, the finish of the next one is connected with the beginning of the previous one. When planning a relationship, you can enter lead time or delay time. The delay time creates a pause between the predecessor action and the successor action. The Gantt chart is the most important tool for designers. The schedule allows you to plan and coordinate the work of teams, agree on the delivery dates of equipment and materials, monitor the actual performance of work with the planned, make corrections to the planned work if the project starts to fall behind the schedule or costs exceed the budget, in order to focus available resources on the performance of tasks that will allow fix problems and eliminate delays.
