Now, they have a customer BigIndustries located in London.
The old projects were developed at London, Frankfurt and
Cologne.
But now, there is also a possibility to assign some work to
Bangalore.
The design and architecture has already been developed and
they want to distribute the development work.
11. Systematic Task Allocation Evaluation in Distributed Software Development
Approach
Approach Overview
Goal 1 : Identify the project specific influencing factors for a
task allocation decision and their impact.
Goal 2 : Evalvate the possible task allocation alternatives
according to the project specific influencing factiors.
12. Systematic Task Allocation Evaluation in Distributed Software Development
Process Steps
Define Viewpoint
Define Viewpoint
Decide who should be making the decisions.
.
Scenario : At GlobalSoft, the task allocation is done by the
responsible project manager. He was also incharge of the previous
projects of BigIndustries (and the customer was happy :) )
13. Systematic Task Allocation Evaluation in Distributed Software Development
Process Steps
Define Context
Define Context
Define the input for the task allocation decision
.
Scenario : The context of the project is developed as shown.
14. Systematic Task Allocation Evaluation in Distributed Software Development
Process Steps
Define Focus
Define Focus
What is the criteria of the evaluation...? Cost..? Quality..? or
something else..?
.
Scenario : At GlobalSoft, the only criterion is the total
development costs. But, how do we define this ”Development
cost”..?
15. Systematic Task Allocation Evaluation in Distributed Software Development
Process Steps
Define Variation Factors
Define Variation Factor
Variation factors are all those factors that have an
allocation-dependent influence on the evaluation criterion.
.
Scenario : The variation categories were identified as:
1 Site characteristics: Analyst capability, programmer capability,
language and tool experience, personnel continuity, customer
proximity.
2 Site dependencies : Cultural dependencies, time-zone
differences
3 Task characteristics : Size
4 Task dependencies: Coupling
5 Task-site dependencies : Application experience, platform
experience

Process Steps
Define Baseline
Define Baseline
The goal of this step is to define the baseline for scuccess measures.
Its on what basis you would decide to allocate the tasks..??
.
Scenario : GlobalSoft uses COCOMO II model to establish a
baseline.
17. Systematic Task Allocation Evaluation in Distributed Software Development
Process Steps
Define Impact of Variation Factors
Define Impact of Variation Factors
In this step, the impact of every variation factor on every criterion
in focus is evaluated.
.
Scenario : GlobalSoft uses a CoBRA approach for cost estimation.
18. Systematic Task Allocation Evaluation in Distributed Software Development
Process Steps
Assess the Variation Factors
Assess the Variation Factors
For all tasks and sites identified, the values of the variation factors
are now assessed for the project in hand.
.
Scenario : The project manager assesses all the factors and print
them into an excel model.
19. Systematic Task Allocation Evaluation in Distributed Software Development
Process Steps
Evaluate Assignment alternatives
Evaluate Assignment alternatives
Finally every possible assignments can now be evaluated using the
results from the previous steps.
.
Scenario : The manager proposes 3 alternatives:
1 Assign all the work to Europe
2 Assign testing work to India
3 Assign everything to India

Assumptions made in the paper
Assumptions made in the paper
In the paper, the author makes assumptions based on an optimistic
scenario.
.
In real world all necessary information about the relavent
influencing factors and their impact are not available in a
quantified form.
.
The selection of total development cost as the only criterion may
have made the numbers but this doesn’t happen in the real world.
.
The available knowledge is never quantifiable.
.
It also assumes high degree of freedom in task allocation decision.
