WEB1P Lecture 2 Introduction, web project management & risk management
Web project management • How are web projects special? • Activities in creating a web site • Project management methodologies • Project life cycles • Activity planning
What needs to be done? • Business content – e-commerce aspects • Presentation – content on web site • Technical content – client-side, server-side programs, databases etc • Server configuration • Site naming, capacity, security, maintenance planning, content management……
Project initiation and PID Requirements engineering System design Software construction Hardware purchase Integration and system testing Installation and cut-over Project close-down Maintenance Stages in traditional IS development
Feasibility study/web strategy Project initiation/assemble team Define site requirements, characteristics Plan site: architecture, functions, appearance Plan and acquire content Create/acquire supporting software Acquire and commission web server/ ISP agreement Site test, launch and handover Maintenance/update of site Evaluation Typical activities for website development
Lack of standards for development Short time-scales (1 – 6 months) Interactive development More diverse teams Parallel working Outsourced jobs Problems with communication and coordination Use of new tools and technologies What is special about web projects?
Piecemeal development can have undesirable effects • Consider a framework for organising development • This is known as a Project Management Methodology • Takes tasks from project life cycle.
Existing methods • Answer the question: What do traditional methods do to help web site development? • Life cycles: waterfall, Boehm spiral, prototyping • PRINCE2, Agile methods: DSDM, Extreme programming, RAD, JAD
Project life cycles • …or SDLCs (System Development Life Cycle) • Relate to IS development • Can they be applied to web development?
THE WATERFALL MODEL Analysis Design Implementation Maintenance
Prototyping • Prototype = working model of one or more aspects of the new system • Constructed to test or validate understanding or assumptions • Prototyping integral to agile methods such as JAD, RAD, extreme programming • Types of prototyping: • Throw-away prototyping • Evolutionary prototyping
PM methodologies • Structured, e.g. PRINCE2, SSADM • Agile/Prototyping, e.g. RAD, DSDM • “Socio-technical” e.g. Soft Systems Methodology
PRINCE2 Concepts • PRINCE2 distinguishes between • Technical task of delivering products • Management aspects • Involvement of the End User (EU) throughout • Scopes projects using work breakdown structures and stages • Can be tailored to different types of project
PRINCE2 Stages • Large project divided into stages to provide regular formal assessment points • Stages produce specific products • Exception reports if tolerances exceeded • Mid-stage and end-stage assessments • Stages end at key control points – project board gives approval to move onto next stage
Advantages Controlled and organised start, middle and end Regular reviews Involvement stakeholders Good communications channels Disadvantages Time-consuming? Too complex for most developments Expensive? Advantages and disadvantages of PRINCE2
Agile methods • Acknowledge need for flexibility • Focuses on keeping code simple, testing often, delivery of components as soon as they are ready • Client approval as project progresses • Take into account the way teams work • Emphasis on communication and collaboration
Dynamic System Development Model • Developed from Rapid Application Development methodology • Most project methodologies deliver functionality at expense of timescale and cost • DSDM prioritises functionality to meet timescale and cost (MoSCoW) • (www.dsdm.org)
Core techniques • Time boxing • MoSCoW prioritisation • Modelling • Prototyping • Testing
DSDM - MoSCoW • M = Must haves – critical to project success • S = Should haves – important but not critical • C = Could haves – could be left out with impacting on project • W = Won’t haves – can be left out and done later
Advantages Control User involvement Direction Prototyping Testing Disadvantages Buy-in by Organisation and people New roles and processes - training Need full application of principles Knowledge and skills to apply Suitability of project DSDM – Advantages and Disadvantages
Website development - Typical activities • Feasibility study/web strategy • Project initiation/assemble team • Project initiation document • Work planning (WBS, schedule, resources) • Define site requirements, characteristics • Use-case scenarios • Wireframe prototypes
Plan site: architecture, functions, appearance • Content • Content map • Plan and acquire content • Technical • Create/acquire supporting software • Infrastructure planning • Acquire and commission web server/ ISP agreement • Site test, launch and handover • Maintenance/update of site • Evaluation
Intangibles: • Agree content format, sources, delivery dates for content providers • Capacity planning and server configuration • Security planning • Implement change control/content management • Determine site performance metrics • Determine maintenance types and schedule • Plan for evaluation
Current ideas for website development • Often combination of Waterfall and prototyping project life cycles, some working in parallel • “Agile” methodologies used for development • Workflow – borrowed from editing industries • Benchmarking – experience from previous projects, other web site developments • Need for experienced staff

Activity planning • Why we plan the development activities • Creating a project schedule • Work breakdown structure • Gantt chart • How do you produce plans • Have a go • Two tools……
Work breakdown structure • Reduces complexity by breaking work down into manageable parts • Helps identify main stages of work/reduces risk of forgetting stages • Ensures tasks happen in the right order • Reduces risk of repeating tasks

Gantt chart • (Hentry Gantt, American engineer) • Shows WBS against a time axis • Shows duration of each task • Shows dependencies between tasks • Used to show when the project will finish • Used to monitor progress
