 Hi everyone, I am Mr. Satish Thalange, Assistant Professor, Department of Civil Engineering, Washington Institute of Technology, SolarPool. In today's session, we are going to see the project management using Gantt chart, learning outcome. At the end of the session, the students is going to be able to develop and compare the Gantt chart of the schedule activity of the project with the milestone chart. Now we will start with the project and the project management. Now project, a project is nothing else, it is a unique process in which a series of activities are present. They are sequenced and they are designed and organized in such a way that the particular project should be complete within the constraints of the time and the specific budgetary and the resource availability. Here, what is the project management? It is a function of the, you can say the leader or a particular project manager to use his practical knowledge and experience along with the applications of a skill and the technical tools and methods for the carrying out the activities of the particular project. Here he tried to cohes a force of overall team towards the completion of the particular project. The project management techniques. Here, the project management techniques are nothing else, it is a graphical presentation. In this, we see the Gantt chart that is also known as a bar chart and the milestone chart. And the second one is a network technique in which we see the CPM that is a critical path method and the PER that is a program evaluation review technique which are the network technique. Now let's see the history of chart for the management. The Henry Gantt was an American engineer, a management consultant and the social scientist who has derived the chart that is a bar chart as himself he has derived the name it is given as a Gantt chart. He has worked with the F.W. Taylor who is the father of scientific management. He has used this technique for the production in the World War I. And he has also used this technique for the planning of the hover dam as well as interstate highway connectivity constructions. Now the Gantt chart, a Gantt chart is a graphical presentation of the project and its activities. In this, we see the horizontal axis which is representing the duration and the vertical axis which is representing the activities. Here the bars which are present in these two axes are nothing else it is an activity representation and the length of the bar is representing the time required for the completion of the activity. Now before going to start the construction of the particular Gantt chart, the following important is what there is a time estimation of the particular activity. Now the following point should be considered for the time estimation of the activity which will finally derive the particular project duration. Here once we define the project we have to define the activity present in the project and their sequence. This can be done by the work breakdown structure. After this we have to estimate the activities resource requirement in which we come to know what are the resources required for the completion of the particular activity and see the availability of the resource available with the particular company or you can say the organization. After knowing the availability of the resource we can estimate the activity duration. The activity duration can be estimated based on the analogous estimating a parametric estimating 3 point estimating or you can say the expert experience as well as judgment. After that finally we have to schedule the particular project. In the scheduling we assign all the resource to particular activity and after that we have to monitor and we have to have the control on that particular activities of the project. Here with the help of the above points finally we can obtain the activities and their interdependency and the resource the reverence required for the completion of the activity which will help us to construct the graphical representation of the particular project. Now this is a particularly traditional presentation of the building project. Finally the particular manager used to present the particular project in the text form. As it is shown in the table he has to list the particular activity present in the project the starting time or you can say starting duration and the duration required for the completion of that particular activity. But this was somewhat a particular means it was particularly there was a deficiency of the reading of the particular project periodically. To overcome this the particular Henry Gantt developed the Gantt chart that is a bar chart which is a graphical presentation. This is a Gantt chart presentation of the particular project. Here we see that the horizontal axis is representing the duration and the vertical axis is representing the activities. Here we see the green color bar with certain thickness but the thickness is nothing it is a only consider for the representation but the length of the particular bar is nothing else it is a time required for the completion of the particular activity. Here each bar on which I have presented the text that is a 5, 7, 2, 2, these are nothing else these are the time required for the completion of that particular activity. Again this is a second graphical representation that is the milestone chart. Here the particular same project I have represented by this milestone chart. These milestones are nothing else if they are representing the starting and the end and secondly they can show the progress of work by showing the second milestone chart which is in the blue color. Here we will compare the Gantt chart and the milestone chart. First of all the most important thing is what the bar chart is a representation of the bars and the milestone chart is a representation of the milestones. The most important in the particular Gantt chart and the milestone chart is what here we will not show any key events but in the milestone chart we show the key events that is a major difference between the particular Gantt chart and the milestone chart. Another one is what here we won't show any key events or you can say the sub activities in the bar chart but here we can show the sub activities in the particular milestone chart. Here we show the progress milestones also which is presented in this particular chart by the blue color milestone. These are the major difference between the Gantt chart and the milestone chart. Now let's see the advantages of Gantt chart and the milestone chart. The advantages of the Gantt chart and the milestone chart are nothing else it is a graphical representation which is easy to construct and it is easy to read or you can say understand by the normal person also. Here the particular team or the particular person can read it and understand easily. There will be a good communication and the coordination among the project team and finally they can easily monitor and have the control on what actually is there and what was planned and help us to a team leader or the particular person to make a decision easily. Now the disadvantages of Gantt chart and the milestone chart here the most important is what we cannot show the interdependency of the activities or tasks. It is hard to construct for the complex or the large projects. Here it is a time consuming also here we cannot show the critical activities and the critical activities interdependencies also. Here we can't represent the resource assigned to the particular activities also we cannot level the particular resource. These are the major disadvantages of the Gantt chart and the milestone chart. Now let us select the correct answer for the particular questions, pause it and select the answer. Hope so you have selected the correct answer which are mentioned by the arrows. These are the references. Thank you.
