The Need for Planning: Implementation Planning William Tibben SITACS University of Wollongong. August 2002
Outline • Definition • Important Questions that you need to ask during Implementation Planning Phase • Building Project Networks • What is a Critical Path and why are these important
‘…Spectacular achievements are always preceded by calculated preparation…’ (GCRH, 2002)
How long is a piece of string? Management says we need a piece of string….but ‘how long is a piece of string? Implementation Planning is required to define • how long the string will be, • where you will get the string, • who will cut it and • how much this will cost.
Definition • ‘…Implementation Planning ensures the compatibility of the planning and budgeting processes to support …[strategic goals]…It prescribes commensurate milestones, resource requirements, schedules and performance criteria at both the program and task levels…’ (NASA, 1996)

Implementation Planning is an Information Intensive Process There is a need to communicate both • the detail • the vision
Implementation Planning is an Information Intensive Process • Implementation Planning (Gray and Larson, 2002, p.89) • provides the basis of scheduling labour and equipment; • determines how much money is required • becomes an instrument that melds managers and groups together into meeting time, cost and performance objectives • answers the question how long is it going to take?
Information Intensive Processes are usually… • Information Intensive Processes are usually those that must deal with a high degree of uncertainty. We must try to fill this void (create certainty) with information. • With that we are plagued with the normal information management problems of communication, structuring information, information overload, tacit knowledge etc…
Practical Example of an Implementation Plan • Northern Territory University’s Callista Project (Student Records System)
Essential Question 1.(Courtesy of Commworks, 2001) • What is the timeline for networkdeployment?
Essential Question 2 - Does your budget support the timeline? Work package cost estimate Gray & Larson, 2000, Figure 3-8

Essential Question 4 - Who will do the work required to deploy the network?
Essential Question 5 - Do you have a strong Project Manager in place to coordinate aspects of deployment?
Essential Question 6 - Who will manage all of the vendors needed for deployment?
Question • Are Implementation Planning processes the same for small projects as for large projects?
Risk Cost High Cost to fixrisk event Chances of risksoccurring Low Project life cycle Project Network • ‘…The project network represents ¾ of the planning process…’ (Gray and Larson , 2000, p. 90). Why? Gray and Larson, 2000, Figure 5-1

The Project Network melds managers, workers…together • Level 1 – Milestones – used by Project Management, Top management and the client. • Level 2 – Work packages shown in relation to each other for Department Managers • Level 3 – Work packages used by first-line managers

Constructing a Network • Networks flow typically left to right • An activity cannot begin until all preceding activities have been completed • Arrow on each network indicate precedence and flow. Arrows can cross over each other • Each activity should have a unique identification number • An activity number must be larger than that of any activities that precede it. • Looping is not allowed • Conditional statements are not allowed • A common start and end node clearly delineates start/finish respectively

Critical Time Path & Free Slack • The Critical Time Path is the longest path through the network. If one of the activities on this path is delayed the project completion time will be extended. • Free slack refers to those activities that are not critical and who’s start/finish time can be varied (e.g to suit resource allocation)
Calculating Critical Time Path & Free Slack • Forward Pass (start with first activity) • How soon can an activity start? (Early Start – ES) • How soon can the activity finish? (Early Finish – EF) • How soon can the project finish? • Backward Pass (start with last activity) • How late can an activity finish? (late finish – LF) • How late can an activity start? (late start – LS)

Scenario 1 • A Project leader for a television news organisation had been working on a major refurbishment of the operational area. The changes included new data cabling and new terminals for about 20 journalists. New video and audio facilities were to be provided to enable journalists to monitor news from other stations. The plan was to move all operations to another floor while work took place. Projects groups were surprised to learn one day that the project manger was redeployed and that the new project manager had been given the directive to get the work done over a single night. This was subsequently organised and executed 2 months later. Though the new installationsuffered minor ongoing commissioning problems for some months after, the change in project implementation schedule was generally viewed as a success. • Why was this so?
Why shorten the critical path? • Imposed project finish date: • Unforeseen event • Political or marketing reason • The need to get a software product out in order to grab market share • Shortening the critical path will usually result in higher cost.

How to shorten the Critical Path • Reduce quality (not recommended) • Use better technology (machine, methods etc) • e.g Outsource • Work longer hours • Reassign labour to critical path activities (eg outsource non-critical activities to enable internal specialist staff to be redeployed). • A management and communication penalty exists if too many people are required to coordinate their activities within a single task.
