    Explain The following approaches
    to resource scheduling

    • Resource Smoothing (10 Marks)
    • Resource Levelling (10 Marks)
    Resource smoothing is used when the
    end date of the project cannot change so we are time constrained. Smoothing
    makes use of free float and total float reallocate the resources allocated to a
    task around without having impacting the overall delivery schedule. For example
    if we have a task which is originally scheduled to use 3 resources for 2 days,
    by making use of float we can use 2 resources for 3 days).
    Resource levelling is different
    from resource smoothing as tasks are on the critical path. Therefore any
    changes to the schedule and the completion of the tasks will mean a delay
    within the overall project delivery as there is no float available. Resource
    levelling should only be considered when all other options have been exhausted
    and no additional resource is available as it will make delivery of the project
    late. 
    Explain 3 approaches / tactics
    which a project manager might consider when optimising the resource allocation
    for a project (identify in your answer any assumptions / implications made) –
    30 marks
    De-scoping – If resources
    available and the timescales for delivery are fixed then the project manager in
    conjunction with the sponsor may look to de scope some of the activity. For
    example the implementation of a new computer system for a call centre must have
    functionality to enable for queries and orders to be dealt with effectively,
    but may choose to de scope up selling capability in order for the project to go
    live. This may be because the outgoing system simply must be replaced because
    it is no longer supported.
    Splitting Tasks – The splitting
    of tasks can be utilised when a resource is simply not available when it is
    required to perform the activity. This can typically happen when a precious
    resource  such as an expert may not be
    available for a 5 day task in one continuous chunk but can do 3 days one week
    and finish the task a couple of weeks later. This may allow delivery to be
    achieved without affecting overall delivery, but this is less efficient as
    their will be a mobilisation / re mobilisation effort associated.
    Working Overtime – When the project
    needs to be completed and there is no possibility to extend the deadline or
    bring in additional resource at short notice. The advantages here are that there
    is no handover of task to another resource needed. However the project manager needs
    to be aware of working time regulations and the possible negative impact on
    productivity if the use of overtime is becoming a regular occurrence to meet
    deadlines.

    Brian, yes you have it right. Smoothing is within the float, levelling effects the critical path.
