Project Management Introduction and some useful tools
What is a Project • Specific, finite task to be accomplished • Traditionally, people view a project as something that produces a physical output • A computer system is an example
What is a Project • Projects can also be viewed as ‘vehicles for change’, the outputs of which may be both tangible and intangible: • physical products • changes to business shape or culture e.g. TQM • improvements in performance or service levels
What is a Project • Usually a one time activity with a well defined set of desired results • It may be divided in to sub-tasks that must be accomplished in order to achieve the project goals
What is Project Management • A clear distinction between project and line management • Line Management: • maintaining existing processes and services • performing within defined roles and jobs • process of continuous refinement and evolution
What is Project Management • Project Management: • is about change • projects tend to be one-offs • have defined time periods with no rehersals • projects require management which can: • adapt to conflicting pressures • adapt to changing requirements • adapt to unfamiliar situations
Why Project Manage • Focus responsibility and authority • Project Manager should: • identify and correct problems at an early date • make timely decisions about trade-offs between conflicting project goals • ensure managers of specific tasks do not optimise the performance of specific tasks at the expense of the total project
Project Network Techniques • For the planning and control of projects with a definable start and finish • Two forms: • AoA - Activity on Arrow • AoN - Activity on Node
PNT - AoN • Given the precedence table, draw an AoN project network highlighting: EST, LST, Duration and Float • Your solution should indicate: • critical path • Total project time (TPT)
Activity Depend upon Duration X - 0 A X 8 B A,C 9 C X 3 D X 12 E X 4 F B,D 11 G D,F 14 Z E,G 0 Precedence Table
Configure the logic of the network... A B C F X D G E Z
Insert duration and dependency times... 8 0 A B 8 9 9 0 3 C F 3 11 11 X 0 12 0 D G 12 14 14 0 4 E Z 4 0
