    CONCEPT

    Planning is the process ofquantifying the amount of time and

    resources, and the size of the budgetfor the project. The output of theproject planning process is a projectplan that a project manager can use tomonitor and control the project teamsprogress.

    Monitoring are the process involvesdetermining what information to collect,how, when and who will collect theinformation, analysis the info and reportingthe current progress.

    Controllingis a process of comparing theactual performance with baselineperformance and discerning any deviation.

    This deviation must be analyzed and suggestthe solution to bring the schedule back ontrack.

    REASONS FOR PLANNING AND

    CONTROLLING To know whether the project turn out to be good or

    bad

    To know whether it costs more than your clientthought it should be

    To know if it took too long to complete To communicate information to people

    To define the sequence of activities to make theoptimum use of resource

    To persuade people to complete task before theydelay subsequent activities

    To provide a framework for decision making in eventof change

    SCHEDULE ORIENTED PLANNING

    (WBS) WBS = is a hierarchical outline (map)

    that identifies the products and work

    elements involved in a project.

    2 basic techniques -i. Bar chart/Gantt chart

    ii. Network diagrams

    i. BAR CHART/GANTT CHART.

    A graphic representation of project

    activities shown in a time-scale bar

    lines with no links shown betweenactivities.

    Popescu and Charoenngam, 1995

    Named after their inventor HENRY L.GANTT in 1917.

    THE ADVANTAGES OF GANTT

    CHART/BAR CHART

    Easy to prepared and understand by workers

    Overall view for the project can be shown at

    early stage of construction.

    Work progress can be mark easily on chart.

    Easy to understand and as controlling device.

    Basic for calculating the work value versustime and preparing cash flow.

    THE DISADVANTAGES OF GANTT

    CHART/BAR CHART

    Linkage between the activity are invisible.

    No information on work flow and priority.

    No certain flow/link which connected one

    activity to another. Any delay will not show

    effect to overall project progress.

    Any changes or review on chart will not show

    effect to overall project progress

    CRITICAL PATH METHOD (CPM)

    A logical and chronological graphic

    representation of the activities and events

    composing a project.

    Basic component :

    i. Arrow : represent logical linkages

    ii. Node : represent activities and detail of

    time

    iii. No dummy activities

    THE DISADVANTAGES OF CPM

    The linkages are quite difficult tounderstand. Certain exercises and courses

    are required and usually not suitable for

    small & medium firms.

    Difficult to understand by site workers.

    Usually, be replaced by bar/Gantt chart.

    Only suitable for big/huge and complex

    projects.

    21/74

    TERMS AND DEFINITIONS Activity = work include time & resources

    event = nodes shows the beginning and ending ofactivities

    Arrow = represent activity & direction to bigger nodes

    Dummy = fake activity just to explain logic in progress

    Duration = time provided for each activities Earliest start/finish = earliest date activity can start

    Latest start/finish = latest date activity can start

    Total float = time adjustment for activity w/o

    effecting the overall duration of the project TF= LSES @ LF - EF

    Critical path = continuous chain of critical activitiesfrom the start to the end of the project. No floatallowed

    22/74

    RULES FOR COMPILING CPM Start and finish with a single activity

    Plot activities horizontally along the paper andlink activities in logical sequence.

    Determine dependency of each activity on otheractivities and link as necessary

    All activities should start at the earliest timepossible

    Once dependencies are complete, insert the

    activity duration Examine the potential for overlap of activities,

    as this will reduce overall programmed duration

  • 8/12/2019 3rd-topic

    23/74

    RULES FOR CRITICAL PATH A Sequence which one activity should started

    right after the completion of previous activity All activities in critical path must fully utilized

    the time provided.

    Must be the longest path along the process At least one critical path per every project

    All activities in this path are not subject toany float

    In case of any changes in critical path,modification will conclude all activities.

    Typical S-curve plotted comparing budget andactual costs.

    S-curves examine the progress of the projectand forecast expenditure in terms of manhours or money. This is compared with theactual expenditure as the project progresses orthe value of the work done.

    All project regardless their size are plottedagainst the same parameters and characteristiccurve can be more readily seen.

    S-CURVE

    S-curve has three significant variables that

    need analyzing, time, moneyand the Sshape(known as the route)

    Since the S shape or route has been foxed,

    then only two variable left to be analyzed. The route is as much as a target as the final

    cost. If the movement month to month is

    compared then the trend can be derived.
