Title: People themes in information systems development


1
IMS5006 - Information Systems Development
Practices
  • People themes in information systems development

2
The role of people in ISD
  • importance of user involvement/participation in
    systems development
  • user/developer communication and cultures
  • the developer as technical expert
  • lack of user satisfaction and commitment
  • technical success is not enough
  • user vs IT department relations

3
The role of people in ISD
  • Some potential solutions
  • Participative approaches
  • Management commitment/leadership
  • Improved human-computer interfaces
  • Training and education developers and business
    users
  • End user computing
  • JRP and JAD sessions

4
People themes in IS development
  • User participation
  • End user computing
  • Stakeholder analysis
  • JAD (Joint Application Development)
  • Groupwork and groupware

5
People themes in ISD
  • in what ways have information systems development
    methodologies been influenced by these people
    themes?
  • how have techniques and tools relating to these
    people themes been incorporated into
    information systems development methodologies?

6
User participation
  • early systems development approaches
  • - focus on technical aspects of computer systems
  • - little actual decision-making by users
  • problems
  • - users resented developers as outsiders with
    little understanding of the business environment
  • - systems imposed on users and not user
    friendly
  • - systems did not adequately support business
    needs

7
User participation definitions
  • participation as user involvement in systems
    design
  • a process in which two or more parties
    influence each other in making plans, policies or
    decisions. It is restricted to decisions that
    have future effects on all those making the
    decisions or those represented by them
  • (Mumford 1983, p. 22)
  • participation may have different meanings for
    different groups
  • e.g. morally right, employee commitment,
    management tool, empowerment of employees etc.

8
User participation definitions
  • Barki and Hartwick (1989) distinguish between
  • user participation
  • a set of activities and behaviours performed by
    users
  • user involvement
  • a subjective, psychological state when a user
    considers a system to be both important and
    personally relevant
  • How do these affect system usage and user
    satisfaction?
  • How can we define and measure user
    satisfaction?

9
Mumfords three levels of user participation
  • three levels are identified by Mumford (1983)
  • consultative
  • all users are consulted about/contribute ideas
    to the design process but the design task is
    carried out by systems analysts
  • representative
  • design groups formed from elected or selected
    representatives take design decisions
  • consensus
  • design group members constantly discuss ideas
    and solutions with all users

10
User participation
  • expected benefits of user participation
  • improved system quality
  • more complete, accurate requirements
  • provides expertise about the organisation
  • avoids development of unacceptable or
    unimportant features
  • improves user understanding of the system
  • increased user acceptance
  • realistic expectations
  • arena for conflict resolution
  • users more committed to the system
  • decreased user resistance

11
User participation
  • Avison and Fitzgerald (2003)
  • user participation has been growing
  • managers should provide leadership by example
  • better user / developer communication
  • systems analysts need to understand business
    areas
  • Improved human - computer interface
  • Enid Mumfords three levels of participation
    (ETHICS)
  • potential problems fragmentation of user groups,
    developer resentment, power relationships

12
User participation and ISD methodologies
  • Structured analysis
  • user walkthroughs, users select implementation
    option
  • SSADM
  • user walkthroughs, user representation in
    development teams, users select technical option,
  • Information Engineering
  • users active in design activities, management
    involved in ISP and BAA, user reviews
  • SSM
  • users part of team problem owners and solvers
  • ETHICS
  • users do the design

13
End-user computing
  • Enabled by PCs and application packages for
    non-IT people
  • e.g. spreadsheets, database, VisualBASIC etc
  • Users in business organisations were able to
    build their own business applications, either
    stand-alone or integrated with organisational
    systems
  • Definitions of end-user computing
  • e.g.
  • the practice of end-users developing,
    maintaining, and using their own information
    systems
  • (Mirani and King 1994)

14
End-user computing
  • Early 1980s user-driven computing
  • -end-user computing enabled by introduction of
    PCs
  • -decentralisation of computing resources
  • Resulted in user satisfaction
  • -met needs unlikely to be satisfied by IT
    departments
  • -some pressure off IT departments
  • -end-users close to the business problems
  • -systems resourced/costed within user
    department budgets

15
End-user computing
  • problems of control
  • validity and integrity of data
  • lack of documentation
  • security issues
  • maintainability
  • application islands
  • duplication and inconsistencies
  • assistance required by users

16
End-user computing
  • A solution Information Centres
  • -Staffed and run by IT department
  • -Provide consultation, software and tools,
    liaison with vendors etc. to assist users in
    developing their own departmental information
    systems
  • Significant in 1980s and early 1990s
  • Increasingly sophisticated users of today have no
    need for Information Centres
  • Users today need support from IT corporate
    specialists when developing customer-oriented
    systems in particular
  • i.e. change from the tactical, problem-solving
    role of the past to a strategic, consultant role

17
Stakeholder analysis
  • Stakeholder
  • Those groups either vital to the survival and
    success of of the corporation or whose interests
    are vitally affected by the corporation
  • Smith and Hasnas (1999) in Avison and
    Fitzgerald (2003), p. 278
  • Seven primary stakeholders
  • Shareholders and investors
  • Employees
  • Customers
  • Suppliers
  • Trade associations
  • Environmental groups
  • Public groups (government, communities etc.)

18
Stakeholder analysis
  • Unstructured identification of potential
    stakeholders e.g. brainstorming
  • Consult/involve those identified
  • Problems
  • primary stakeholders easy to identify
  • accountability to stakeholders
  • Establishing legal, moral rights e.g. privacy,
    risk
  • Stakeholder interests difficult to define e.g.
    subjective, unclear (interorganisational/global)
  • Balancing of stakeholder interests
  • A managerial imperative leads to successful
    systems

19
JAD (Joint Application Development)
  • can be for analysis and/or design
  • originated in late 1970s at IBM
  • bring together key users, managers, systems
    analysts in a group meeting with a specific
    structure of roles and agenda
  • JRP (Joint Requirements Planning) key system
    requirements
  • JAD specify the systems design (external design
    only)
  • group meeting
  • avoid distractions
  • identify areas of agreement and conflict
  • resolve conflicts during the period of sessions

20
JAD sessions roles
  • JAD participants
  • facilitator organise and run the sessions
  • scribe(s) takes notes on a PC, CASE tool etc
  • users understand the system requirements
  • managers organisational overview
  • systems analysts technical knowledge,
    learn about the system
  • sponsor senior executive who commits and funds
    the process

21
Joint Application Development
(JAD)
  • JAD sessions
  • from one to five days
  • structured meeting room with white boards etc.,
    CASE tools
  • located away from users workplace
  • outcome is documents detailing the system
    workings of/requirements for the system/design

22
Joint Application Development (JAD)
  • Preparing for JAD sessions
  • JAD leader prepares and distributes agenda and
    documentation about scope and objectives
  • Agenda specifies issues to be discussed and time
    allocated to each
  • Ground rules for running the sessions are made
    clear
  • Ensure users who attend are knowledgeable about
    their business area

23
Joint Application Development (JAD) sessions
  • Conducting JAD sessions
  • Avoid deviating from the agenda
  • Keep to schedule (time for topics)
  • Ensure scribe takes adequate notes
  • Avoid using technical jargon
  • Use conflict resolution strategies
  • Allow ample breaks
  • Encourage group consensus
  • Encourage participation vs individuals dominating
  • Ensure ground rules are adhered to

24
JAD sessions
  • benefits
  • reduced time to move requirements/design forward
    (group vs one-on-one, details worked on between
    meetings)
  • key people work together to make important
    decisions
  • commitment is focused and intensive, not
    dissipated over time
  • conflicts and differences can be understood and
    resolved
  • improved quality and productivity

25
Groupwork and Support Systems
  • a group (or workgroup)
  • 2 or more people (up to 25?) whose mission is to
    perform some task and who act as one unit
  • group support systems
  • systems which support organisational group
    activities, improving their effectiveness and
    efficiency
  • includes
  • CSCW (computer-supported co-operative work) -
    groups of people working together, especially
    professionals working on creative tasks
  • GDSS (group decision support systems) - groups of
    people involved in decision-making tasks

26
Group Support Systems
  • related and overlapping concepts/technologies
  • groupware
  • software products designed to support groups of
    people engaged in a common goal or task
  • office automation
  • technology designed to improve the functioning
    of the office,
  • e.g. word processing, LANs
  • computer conferencing
  • electronic communication allowing two or more
    people at different locations to have a
    conference or collaborate on a task, an aid to
    discussion
  • electronic meeting system
  • IT-based environment supporting a group meeting
    that may be distributed geographically and
    temporally

27

Time/Place Communication Support
Same Time
Different Time
e.g. meeting room
e.g. team room, shared offices (e.g. shift
work)
Same Place
mutimedia presentation systems, keypad-based
voting systems, facilitated meetings using
networked PCs
e-mail, messaging
e.g. meeting
e.g. group task
e-mail, data and file sharing, group
authoring tools, workflow software
Different Place
screen sharing, video conferencing
from DeSanctis Gallupe (1985)
28
Group Support Systems
  • working in groups
  • e.g. committees, teams, review panels, task
    force
  • advantages
  • a group has more information than any one member
  • working in a group stimulates the process, ideas,
    problem solving
  • risk balance moderate high riskers and encourage
    conservatives
  • better at finding errors
  • synergy, accountability, commitment

29
Group Support Systems
  • working in groups
  • e.g. committees, teams, review panels, task
    force
  • disadvantages
  • groupthink pressures to conform
  • tendency of group members to rely on others to do
    the work
  • time-consuming, expensive
  • inappropriate influences domination, fear of
    speaking up
  • difficulties of co-ordination, and need for
    planning
  • non-productive time, e.g. socialising, waiting
    for people
  • compromise, poor quality decisions, lack of
    participation

30
Groupware
  • software tools that support and help co-ordinate
    the activities of a group require their users to
    be connected to a network of computers and
    databases
  • intranets
  • provide access to internal organisational
    information and facilities e.g. e-mail, corporate
    databases, directories, software
  • the Internet
  • provides access to external information and
    communication and collaboration facilities
  • groupware products can be used as separate
    packages or as integrated systems

31
Groupware
  • groupware is an ambiguous term, 100s of products
    on the market
  • integrated systems
  • e.g. Lotus Notes, Netscape
    Communicator
  • separate applications
  • browsers, intelligent agents, search engines
  • electronic mail
  • bulletin boards and newsgroups (email-based
    discussion groups)
  • messaging systems
  • workflow software accessing, tracking, and
    directing documents and information
  • screensharing same material shown on
    participants' screens
  • (e.g. manuscripts, spreadsheets)
  • integrated conferencing services
    teleconferencing, video conferencing

32
Groupware
  • Lotus Notes an integrated system groupware
    product
  • A group communications environment for users to
    access and create information that is collected,
    stored, organised and disseminated on one or more
    networks
  • Direct web access and access to we browsers
  • Provides workgroup email, distributed databases,
    bulletin boards, text editing, document
    management, application development tools, and
    workflow capabilities all integrated using a
    graphic menu-based interface
  • (Windows interface in client/server
    architecture)
