Tabl Aviva Water Totter and spreadsheet can also be us to creat simpl and easi to chang chart without MS Project. Spreadsheet with colour bar ar most us for the simplest projects.
plan and control complex multi stage projects.
Gantt chart ar us tool for analysing.
Gantt Chart can;
A ssist in identifi the task and sub task to be undertaken
Help you lai out the task that need to be completed
A ssist in schedul when these task will be carri out and in what order
A ssist in plan resourc and need to complet the project.
A ssist in work out the critic path for a project where it need to be complet by a particular date.
Gantt chart assist in monitor whether the project is on schedule,When a complex or multi task project is under way. or not. If not, the Gantt chart allow you to easili identifi what action need to be taken in order to put the project back onto schedule.
it is not a good idea to start build the wall in an offic block befor you have laid the foundations; neither is it a good idea to put the cake mix into the tin without greas the tin firstA n essenti concept behind project plan is that some activ ar depend on other activ be complet first. For example..
with each stage be more-or-less complet befor the next stage can begin. We can call such depend activ sequenti Thes ar depend activ which need to be complet in a sequence..
Non sequenti activ ar not depend on the complet of ani other tasks. These activ mai be done at ani time befor or after a particular stage in the project is reached. These activ ar call ar nondepend or parallel tasks.
To creat a Gantt chart;
1. List all activities/task in the plan
show the earliest possibl start date,For each task. how long you estim the length of time it should take, and whether it is parallel or sequential.
show which stage thei depend onIf task ar sequential..
week or month through to task complet on the top X-axis. The y-A xi can be us to itemis each task in it order. You mai want to us an Excel Spreadsheet for thi instead of graph paper if you preferHead up a sheet of graph paper us pencil and a ruler with the days..
2. Plot the task onto the Plan
show it start on the earliest possibl date. Draw each task as a horizont bar,Next list the task in the first column on the left hand side of the page. The Y-A xi To draw up a rough first draft of the Gantt chart; Plot each task on the plan. with the length of the bar be the length of time you estim the task will take. Above each task bar, mark the estim time taken to complet the task. At thi stage there is no need to includ schedul - all you ar do is set up the first draft.
3 Schedul the tasks/activities
lai foundations,Now on a fresh sheet redraw the Gantt Chart to schedul action and tasks. Schedul these in such a wai that sequenti action ar carri out in the desir sequenc e.g. dig holes. begin construct .
Ensure that these depend activ do not start until the activ thei depend on have been fulli completed.
schedul parallel task so that thei do not interfer with sequenti action on the critic path. While scheduling,Wher possible. ensur that you make best us of the time and resourc you have available. Do not over-commit resourc and allow some time in the schedul for holdups, overruns, qualiti rejections, failur in delivery, etc.
you can see how long will it take to complet your project. The kei step to be complet to ensur success complet of the project should be clearli visibleOnce the Gantt chart is drawn..
thei also make subsequ modif of plan easier and provid facil for monitor progress against plans. In practic profession Project Manag us sophist softwar like MS Project to creat Gantt charts. Not onli do these packag make the draw of Gantt chart easier.
