Quality Management: Steer from Top

  • What is Quality Management?

    • The philosophy:

      • mistake should be prevented rather than detected

      • fulfill the stakeholders’ expectations

    • Quality Planning

      • proper project management structure

      • clear definitions of roles and responsibilities

      • determine what quality standards should be adopted

      • need to be set right at the beginning

      • end result is a Quality Plan

    • Quality Assurance

      • planned and systematic quality activities to monitor the project

      • provide the confidence that the project will meet the standards

    • Quality Check

      • measure specific project results to determine that the results match the standards


Quality management steer from top5 l.jpg
Quality Management: Steer from Top

  • Why Need a Project Management Methodology?

    • To define the project organization

    • To reach consensus among all relevant parties about

      • Why the project is needed?

      • What the project is intended to achieve?

      • How, where and when the parties are going to participate?

    • To provide a framework for Quality Management

    • To overcome some common mistakes like

      • Inadequate planning and co-ordination of resources, activities, and scheduling

      • Poor communication among interested parties

      • Under-estimation of project costs and duration

      • Lack of control over progress

      • Lack of quality control


Quality management steer from top6 l.jpg
Quality Management: Steer from Top

  • What is PRINCE?

    • short for PRojects IN Controlled Environments

    • established in 1989 by CCTA (the Central Computer and Telecommunications Agency) in UK, later renamed as the OGC (the Office of Government Commerce)

    • structured method for effective project management

    • widely used in both public and private sectors

    • define the activities to be carried out for project organization, planning, risk management and control

    • balance and optimize among Function, Time, Resource, Quality, and Risk


Quality management steer from top7 l.jpg
Quality Management: Steer from Top

  • Components of PRINCE: Organization

  • The organization usually composes of three parts, namely the Project Steering Committee (PSC), the Project Assurance (PA) Group and the Project Manager (PM).

    • PSC usually consists of Executive, Senior User and Senior Technical

    • PA Group usually consists of Business Assurance Coordinator, User Assurance Coordinator and Technical Assurance Coordinator

    • The PM, to whom all other team members report, is responsible for the timely production of all end-products to the agreed quality standards within the tolerances of time and cost set by the PSC

  • The role and responsibilities of each member in the organization should be clearly defined in the Project Initiation Document

Quality Management: Steer from Top

  • Components of PRINCE: Planning

    • The concept of 'Staging' is recommended. A project should be divided into stages to facilitate project management and control

      • It provides senior management the opportunities to assess the project progress and business case at the stage boundaries.

      • It also enables more realistic estimates for each stage

    • Product-based Planning is introduced. It encourages planning the products first and then the activities

      • It ensures that the derived activities will directly contribute to the development of the products

      • The project manager should plan on project level for Project Steering Committee to oversee the project and he / she should plan on detailed stage level for his / her day-to-day control


Quality management steer from top9 l.jpg
Quality Management: Steer from Top

  • Components of PRINCE: Control

    • Management by Exception – the principle

      • During a project stage, the Project Steering Committee delegates the day-to-day project management responsibilities to the Project Manager with 'Tolerance'

      • The Project Steering Committee exercises control on project only when there is Exception (has exceeded or is anticipated to exceed the tolerance)

    • Quality Management: the elements

      • Inclusion of Quality Plan (detailing related guidelines/ standards, quality criteria and quality checking method) devised at the project initiation

      • Conduct of Quality Assurance Review at different stages to look for positive evidence that the product meets its specifications and quality criteria


Quality management steer from top10 l.jpg
Quality Management: Steer from Top

  • Components of PRINCE: Control

    • Control Meetings

      • Project Steering Committee Meeting held by Project Steering Committee (event driven or time driven at project initiation, end-stages, project closure)

      • Checkpoint Review held by Project Manager (regular and time driven)

    • Management of Risk

    • Management of Configuration/Change

  • Formal Quality Review


Quality assurance in system development l.jpg
Quality Assurance in System Development

  • Adoption of Standard Methodologies

    • give clear specification of what is to be produced and how it is to be managed and reviewed

    • visualize users' business objectives/activities and needs by continuously involving users with standard modeling techniques

    • promote better quality management by detecting errors early in the lifecycle, especially by involving users as well as skilled practitioners in checking for errors

    • separate logical system specification and physical design to enable portability and re-use of application

    • leverage useful automation tools for productivity gain

    • transfer expertise to practitioners including business and IT managements and users

Quality Assurance in System Development

  • SSADM in Practice

    • Structured Systems Analysis and Design Methodology (SSADM) is established in 1981 by CCTA (Central Computing and Telecommunications Agency) in UK

    • covering the Feasibility Study Phase, System Analysis and Design Phase, Implementation Phase of the System Development Life Cycle (SDLC)

    • an integrated set of standards and guides for the analysis and design of computer systems consisting of

      • Structural standards, which define tasks explicitly, with clearly defined interfaces between them, and clearly defined tangible products

      • Technique guides, which provide a set of proven techniques and tools, and detailed rules and guidelines on when and how to use them

      • Documentation standards, which provide the means of recording the products of development activity at a detailed level


Quality assurance in system development15 l.jpg
Quality Assurance in System Development

  • Major Quality Assurance Related Activities in SSADM

    • Define existing environment, business system option, functional and non-functional requirements (such as response time, capacity, security, contingency measures, etc), technical system option, logical design, and physical design, in both feasibility study and system analysis & design stages

    • The deliverables will be produced and accepted through series of discussions between developers and end-users so as to ensure the end-product is what the business requires

    • Specify various acceptance tests in implementation stage such as Unit Test, System Test, Integration Test, Load Test, User Acceptance Test, etc
