3 Topic of Presentation Resource Allocation

4 Critical Path Crashing Resource Leveling Resource Constrained Schedules Multi-project Resource Management Critical Chain

5 The Resource Allocation Problem Resource allocation is a major problem in a project. In general term we define three major resources allocated to the project, which are: Time Cost Performance Critical path method- Crashing a project CPM and AON allowed the PM to schedule the physical resources to the project. There are tow time and cost specifications are defined for each activity. One is called Normal and other is called Crash.

6 What is Crashing / Crunching? To speed up, or expedite, a project Of course, the resources to do this must be available Crunching a project changes the schedule for all activities This will have an impact on schedules for all the subcontractors Crunching a project often introduces unanticipated problems Time requirement of a task must be determined with an assumption about the level of resources devoted to the task. We need to know what additional resources are needed to shorten the completion times.

7 Slope: while crashing a project, it is the important to consider the relation called slope. It is calculated as:

8 Steps to follow: To crash a project, two steps should be followed. Focus on the critical path when trying to shorten the project Crashing a noncritical activity will not influence project duration.

9 Fast Tracking: Another method for crashing a project is fast tracking. It seems to be reasonable way to expedite construction projects as well as other types of projects when the early build or carrying out steps are fairly routine and well understood. It is a partial use of the basic concepts in the phase-gate project management and is dependant on effective feed-back and feed-forward communication.

10 Resource Allocation problem: The extreme points of the relationship between time use and resource use are: Time limited. Resource limited.

11 Resource loading:  Resource loading is the process of calculating the total load from project task son each resource for each time period of the project’s duration.  It gives a general understanding of the demand, a project or set of project will make on a firm resources.  It is a guide for early project planning and also the first step to reduce excessive demands on certain resources.  The use of the resources on a project is often non linear  The project action plan links the schedule directly to specific demands for resources.  It is the job for the project manager to deal with overloading of resources, either by adding people or by changing the schedule

12

13 Resource leveling: Resource leveling is concerned with evening out the demand for various resources required in project by shifting tasks within their slake alliances. The purpose is to create a smoother distribution of resources usage.

14 Managerial implications: Less management is required if the use of a given resource is nearly constant over its period of use. The PM may be able to use a just-in-time inventory policy without much worry that the quantity delivered will be wrong. If the resources being leveled are people, leveling improves morale and results in fever problems in the personal and payroll offices.

15 Cost implications: When resources are leveled the associated cost also tends to smooth out. If the labor requirements are leveled the organization can save and avoid the hiring and layoff cost.

17 Resource loading / leveling and uncertainty Unexpected delays can occur in the work schedule of a project for multiple reasons. The demand can be leveled by moving some resources forward and some back depending upon the flexibility of the production environment. Trade off can be made between periods of over capacity and the periods of under capacity.

18 Constrained resources The lack of resources where and when needed is caused due to loss or theft failure of a supplier to produce and deliver, assignment of resources to another activity

19 Two fundamental approaches to constrained resource allocation are Heuristic Model Optimization Model

20 Heuristic Model Seek better solutions Approaches to constrained resource scheduling problems in wide, general use for number of reasons Feasible methods of attacking large, non linear, complex problems Schedules generated by this approach may not be optimal PERT/CPM schedule and analyze resource usage period by period, resource by resource Uses priority rule and most common rules include

21

22 Example resource used by activities e, f, g and h in the figure is scarce. To which activity would you assign the resource, based on the following rules? a.Minimum slack b.Most successors c.Most critical followers d.Shortest task first

23 Two events will occur while scheduling heuristic model Routine runs out of activities before it runs out of the resources and excess resources are left idle assigned elsewhere in the organization as needed during current period or applied to future tasks or it runs out of resources before all activities have been scheduled. If minimum-slack-first rule is used resources used would be devoted to critical activities, delaying those with greater slack.

24 Optimization Model Seek best solution but limited in ability to handle complex solutions and large problems Allocation and scheduling of resources depend on sophisticated mathematical and graphical tools Two categories to find optimal solution for resource constraints include linear programming, enumeration and combined programming and enumeration methods.

25 Multi project scheduling and resource allocation Two common approaches to deal with Scheduling and allocating resources are Treat several projects as if they were each element of a single large projects Consider all projects completely independent

26 The important parameters affected by project scheduling are following Schedule slippage Resource utilization In-process inventory

27 Manufacturing process model J = (λ/µ) / (1-λ/µ) λ Arrival rate of the job to be processed by a facility µ facility’s rate of servicing job j average number of jobs

28 Heuristic technique Resource scheduling method Dij = Max [ EF – LS] Priority = dj ∑ r ij Greatest resource utilization Most possible jobs

29 A multi project scheduling Heuristic The most common approach to scheduling and allocating resources to multiple projects is to treat the several projects as if they were each elements of a single large project Another way of attacking the problem is to consider all projects as completely independent To describe such a system properly, standards are needed by which to measure scheduling effectiveness The most common approach to scheduling and allocating resources to multiple projects is to treat the several projects as if they were each elements of a single large project

30 Another way of attacking the problem is to consider all projects as completely independent To describe such a system properly, standards are needed by which to measure scheduling effectiveness Three important parameters affected by project scheduling are: –Schedule slippage –Resource utilization –In-process inventory

31 Selected Project

32 Introduction Project for Improvement of Financial Reporting and Auditing (Revised) was started in Authorities responsible for: (i)Sponsoring: Ministry of Finance (ii)Execution: Office of the Auditor General, Ministry of Finance/CGA (iii)Operation and maintenance: Office of the Auditor General, Ministry of Finance/CGA Time required for completion of project:120 Months (10 years)

33 adopt and implement a modern accounting system designed according to recognized accounting principles and standards and based on modem information technology’; implement a governance structure and legal framework for an independent and effective audit function’; improve the professional capacity of the elements of the civil service responsible for fiscal management’; make increasing use of the private sector to supplement public sector resources’; and adopt improved standards for private sector financial disclosure’.

34 Objectives/ Benefits Modernized government audit procedures and adoption of internationally accepted auditing standards will eradicate program oversights and improve evaluation capabilities. Effective accounting and reporting systems will enable the government to better formulate, control, and monitor its budget. Strengthened financial management practices will increase the impact of development programs and related external assistance. Financial information generated by the improved accounting and information systems will be more useful, complete, reliable and timely. Improved data will facilitate program management by government decision-makers. Tighter internal controls will lessen the occurrence of errors and irregularities in the processing of payments and receipts. Related training programmes will build staff capabilities and enhance utilization of human resources.

Strengthened financial management practices improved accounting and information systems lessen the occurrence of errors enhance utilization of human resources. Indirect and other benefits Contribution towards specific targets/social objectives.

43 Conclusion It went through various phases with varying degree of success in terms of satisfactory progress on achievement of objectives. The key factor that galvanized the project was a professional team having the confidence of the Auditor General. This team brought about fundamental changes in the approach to the project management; professionalism, project culture, engagement, risk taking, aggressive tracking of activities etc. The project has made an impact by training around DDOs, 400 auditors, 2000 SAP end users. One of the key success parameters is that the project has made its presence conspicuous to a point where it is high on Government agenda.
