The risk and the uncertainty rises multifold with respect to the size of the project, even when the project is developed according to the set methodologies. So, when the size of the project will be too big, whenever we are dealing with thousands of tasks, whenever we are having the hundreds of or thousands of resources and then the project will be too much complicated. And there are tools available which aid for effective project management and the new and the few of them are described here. So, that is why we require some project management tool. Manual project management may not work there because the size of the project is too big. So, the tools are NAT chart, part chart and resource histogram. So, you can also have some other charts also, but here we have considered only this main three because they are very much familiar and common as the project management tool in the industry. So, first one is the NAT chart. So, now we are going for the NAT chart. So, please look at the spelling. So, NAT chart but the spelling is G-A-N-T-T. So, NAT chart. So, NAT chart was devised by the Henry NAT in the year 1917. And it represents a project schedule with respect to the time periods. And it is a horizontal bar chart with bars representing activities and time schedule for the project activities. So, here you just consider here we are having the week numbers 1, 2, 3, 4, up to 10. We have written this one. And here are the different project activities. What are they? That is the planning, design, coding, testing and delivery. So, we are expecting that within this within the three weeks of time, the planning will be completed. In the last week, on the last week, this design and the planning can have the overlapping. That means, after finishing the planning, the design will not executed. The design will go on executing on the third week of this planning. So, here we are having one overlapping of this two respective phases. So, coding will start only after designing. So, it will be starting like this. And the testing will be done on the, from the second week of the coding and testing will take, say three weeks of time. And delivery obviously, you cannot do the delivery in parallel to the testing. So, after completion of the testing, then this delivery will take place. And delivery will take another one weeks of time. So, in this way, what is this? This is known as the NAC chart. So, here we are having that time and here we are having different activity lists. And in this horizontal bar diagram, we are representing this NAC chart. So, let us go for the next one. So, here we are having this part chart. So, there is the program evaluation and review technique. So, this part chart can also be known, can also be called as activity network diagram. So, this is the program evaluation and review technique. Do not consider this very program as the computer program. Do not consider that one. If you go for the very early or old edition of this project management books, you can find this one. This part is having the full form that is the project evaluation and review technique. But if we consider the latter version. The latest version of this books on this project management. Software project management. You can find this part having the full form. That is the program evaluation. And review technique. Now, the question is coming in mind, then what is the project? What is the program? And what is the portfolio? So, we know that project, we have defined project multiple times in our tutorial. That project is nothing but one temporary endeavour having a start date and end date. And at the end of the project, we are going to get unique is private project, product, service and results... So, let us suppose just consider a generic way, that is a construction company. And right now, they are executing five building construction projects and three mobile tower efficient projects. So, how many project that is executing? Fiveplus trois... what is that value... eight project that is executing? Now, these five building construction project are alike in nature. So, they will be coming under program Program number one. So, these three mobile tower erection projects, so they are alike. So, I am bringing them in another program, let it be program number two. So, collection of this program number one and program number two and say another discrete unique project. So, might be making the portfolio of the company. So, we have defined a project, we have defined a program. So, program is collection of alike projects and then portfolio means collection of projects and programs will make the portfolio. So, here this particular program evaluation and review technique, this program is actually symbolizing that very program. So, this particular part chart is a tool that depicts project in network diagram and also it is known as activity network diagram. It is capable of graphically representing main events of project in both parallel and consecutive ways. And events which occur one after another show the dependency of the later event over the previous one. So, events are shown as numbered nodes and they are connected by labelled arrows depicting the sequence of tasks in the project. So, just consider this activity network diagram, we have just taken one diagram as an example. So, here we are having multiple activities are there, it might be the activity number. And here we have written the respective durations. So, now if we consider this path. So, we are having two paths here. So, that is one path and if we consider the another path here. So, now what is the duration of this path? So, 5 plus 1, 6 plus 3, 9 days. 3 plus 4, 7 plus 3, 10 days. So, this is the path with the longest duration can also be treated as a critical path in this particular activity network diagram. Activity network diagram, the critical path will decide the project duration. Ok. This activity network diagram or this path diagram can be of 2 types. One is activity on node and one is activity on arc. If you write this durations across the arc, then it is known This is known as activity on arc. So, this particular diagram is actually AOA activity on arc. But if you write this durations across this nodes, then this particular diagram will be in the version that is AON, that is the activity on node. So, now here we are having the resource histogram. So, this is a graphical tool that contains bar or charts representing the number of resources, usually skilled staff required over time for a process. So, this is a project event or a certain project phase. And resource histogram is an effective tool for staff planning and coordination. So, let us suppose we are having this designer, developers, testers and this total we are having. So, day one, day two, day three in this way you have considered only seven days. So, now in the first, so four designers will be required and total is four here. And in the second day, four designers will be continued. In the third day, we are having three designers and one developer, so in total four. So, here we are having three designers and two developers, so total is five. In this way, this table has got populated with the respective values. But it is the tabular representation, not the graphical representation. So, let us go for the graphical representation right now. So, here we are having this resource histogram. So, this is the tester, developer and designer. So, they are having different colors. You can find that on day 1, we require only 4 designers. On day 2, we require only 4 designers. On day 3, we require 3 designers and 1 developer. So, in this way, you are getting this idea that what is the, what are the resources we require on the very daily basis in a graphical representation. So, this is known as resource histogram. So, these are the different project management tools that can be used for the better understanding, for the better graphical understanding of of the project requirements.
