3
Where is this talk coming from?
  • Based on
  • Three years experience of running a large
    institutional website
  • Past research into managing non-WWW information
    in a distributed systems environment
  • On-going research into Information Management
    aspects of Websites
  • aim to survey HE and commercial organisations
  • Currently work-in-progress
  • Disclaimer!
  • All views and opinions are mine wearing my
    academic hat
  • They dont necessarily represent the official
    policy or views of the University

4
A brief history of the UoW Website
  • Experimental webserver in School of Computing,
    April 1994
  • Main corporate webserver in Computer Centre
    since September 1994
  • both of these were effectively uncontrolled
  • Controlled by Marketing dept from mid-1995 until
    end of 1997
  • Marketing sub-contracted the job to me
  • Technical support from Computer Centre
  • Marketing dept withdrew because the Website no
    longer just marketing
  • Current status of website management in limbo,
    pending re-organisation of University IT Services
  • Now appears in job description of Asst. Director
    of IT Services (Standards Developments)

5
Current Status of UoW Website
  • Over 67,500 pages
  • Multiple Servers
  • limited at present, but very likely to increase
  • Highly diverse School Department pages
  • in terms of
  • Content
  • Style
  • Design
  • Quality
  • Usefulness (despite corporate rules and
    guidelines)
  • Shipping over 700 Mb of data a day
  • this may be a better indicator than mere hits

6
The Web Effect
  • A paradigmatic shift in the nature of
    information provision
  • A massive rise in expectations - realistic and
    otherwise
  • Towards the single institutional image
  • Before the Web
  • Multiple information sources producing multiple
    versions of the same information, aimed at
    different target communities
  • prospective students, businesses, etc
  • Information often only available on request
  • e.g. staff phone numbers
  • Many inadequacies in strategic information
    management were hidden
  • because separate individuals deal with separate
    departments

7
The Web Effect (2)
  • Since the Web
  • An information explosion
  • Information initially provided without much
    planning for purpose or audience
  • Information often direct conversion of existing
    physical version
  • Prospectus
  • Course literature
  • Telephone/e-mail listings
  • The Institutional Website is a single
    institutional image
  • Potential for Web as primary information source
  • Information transparency
  • Everything is available to everyone, everywhere

8
Problems with Websites
  • Reflection of internal structure
  • e.g., server hierarchy (and content) structured
    by School Department
  • Internal-only information may be visible
  • Users arent interested in our internal structure
  • What if the internal structure changes?
  • changing URLs is possible but problematic
  • dead-links both inside and outside
  • technical system complexity
  • e.g., symbolic links, server redirections
  • but not changing them perpetuates model of old
    structure
  • Function over structure?

9
Problems with Websites (2)
  • Poor mapping between internal structure and user
    groups
  • e.g. entry to UoW site is currently aimed at
    specific user communities
  • For Prospective Students
  • For Current Students
  • For Staff
  • For Alumni
  • plus other necessary abstractions (About the
    University, Contact Us, etc)

10
Problems with Websites (3)
  • But we dont have a For Prospective Students
    Department
  • We do have
  • A Media Publicity Service (Prospectus)
  • An Admissions Unit
  • An International Relations Office
  • A Students Union
  • 10 Academic Schools etc..
  • The overall provision of information needs to be
    managed - but how?
  • Hope for the best? (more chaos?)
  • Create a new department to do it ? (more
    bureaucracy?)
  • Co-ordinate autonomous departments? (more
    bureaucracy and chaos?)

11
Problems with Websites (4)
  • Web information is different ...
  • Conventional information provision is essentially
    linear and structured by the provider
  • Written/Printed
  • Spoken
  • Web information is non-linear and (despite
    careful design) is effectively re-structured by
    every user
  • Multiple entry points
  • Multiple pathways
  • It therefore demands a different approach
  • But how many web authors have studied hypertext
    theory
  • ... and can apply it?

12
Problems with Websites (5)
  • Currency of information
  • If it isnt managed, how do you know?
  • Move from Last Modified to Valid Until dates
  • Treats information like food (Best Before)
  • Helps promote a more active culture of
    maintenance
  • Checking can then be automated more easily
  • especially if metadata is used (but thats
    another talk in itself)
  • Maintainer must be identifiable and contactable
  • Preferably an actual person, not just a job title
  • Someone must be actually responsible
  • The author may not be the maintainer
  • No good shooting the messenger
  • How often is this sort of information ever
    checked and enforced?

13
Problems with Websites (6)
  • Search Engines and external links
  • Dead links often exist for long periods
  • First 100 or so Alta Vista relevant links were
    to our 1996 and 1997 prospectuses
  • Our 1998 Prospectus isnt even called that
  • its an Essential Guide, but people dont
    search for that
  • Some search tools now contain historic
    snapshots of the web
  • Out-of-date (and therefore invalid) information
    may be preserved for long-term access

14
Problems with Websites (7)
  • Websites actually cost money
  • This can be a revelation to management
  • How do you cost a website?
  • How much does it cost to author a page/site?
  • How do you perform a Cost Benefit Analysis for a
    website?
  • What proportion of peoples jobs spent authoring?
  • Should they be doing it anyway?
  • Whats the most cost effective way of doing it?
  • Do you know
  • (a) how much your website cost to create?
  • (b) how much it costs to run it?
  • (c) if it is economically viable?
  • But what is the cost of not doing it?

15
Website Maturity Models
  • Based on maturity models of IT systems
  • May help to analyse, predict and plan development
  • or at least identify where it all went wrong
  • Different models from different perspectives
  • Activity
  • functional - whats being done?
  • Stakeholder
  • people - whos doing it?
  • Technical
  • systems and software - hows it being done?

16
Activity Model
  • Doing something - anything
  • a means to an end - getting web experience
  • almost anything is valid content
  • Doing something useful
  • e.g., conversion of existing literature,
    alternative channel for basic information (e.g.,
    phonebook)
  • Doing something professional
  • e.g., contributing to marketing function,
    supporting traditional course delivery
  • Doing something new and creative
  • e.g., a self-contained channel for learning
  • based on Tom Keen, MIT

17
Stakeholder Model
  • Technical
  • Most institutional webservers began in technical
    departments
  • e.g., computer centres, schools of computing
  • Publicity/Marketing
  • Control taken over by marketing or publicity
    departments
  • Institutional prospectus and advertising
  • Information Provision
  • As many stakeholders as channels of information
  • Complexity of website structure tends to
    approaches complexity of organisational structure

18
Technical Model
  • Single webserver
  • usually in central Computing Services or IT
    department
  • Multiple servers
  • usually single platform (usually Unix)
  • Wolves only has 4 servers - some Universities
    have dozens
  • Multiple platforms
  • Unix, NT, Mac - maybe others
  • Extra technologies
  • Plug-ins, SSI, PHP, JavaScript, Java, ActiveX
  • Note Technical maturity does not necessarily
    equal desirability or manageability

19
The Need to Adopt a Consolidated Approach to
Information Management
  • Websites represent a massive growth in
    information provision
  • in terms of both volume and users
  • Web technology enables anyone to publish
    anything, leading to
  • unmanageable complexity
  • consistency and integrity problems
  • accessibility problems
  • non-interoperable systems
  • A Website is a major information resource and
    must be managed

20
1. Recognise the Importanceof Information
  • Recognise that all users - both internal and
    external - can (potentially) access the
    information they require directly
  • a process of disintermediation
  • problem of one source but multiple needs
  • Information previously thought merely internally
    "useful" is now externally visible
  • e.g. internal phone directory updated annually,
    now on-line and real-time
  • Information Audit
  • what information and who controls it - and at
    what cost?

21
2. Distinguish between authenticatedand
unauthenticated data
  • Information can be published at many levels and
    by many people
  • Some will remain under direct internal control
    (and should)
  • Much won't (and shouldnt)
  • the balance depends on other decisions
  • e.g., the degree of decentralisation
  • Who authenticates?
  • The author? (may not have the authority)
  • The provider? (may not have the expertise)
  • Third party? (webmaster? someone else?)

22
Example Information Categories
  • Authenticated Central
  • e.g. prospectus
  • Authenticated Local (Departmental)
  • e.g., HS instructions, Course Regulations
  • Authenticated Local (Individual, Staff)
  • e.g., Module Resource pages
  • Unauthenticated Local (Departmental)
  • variant copies of central information
  • Unauthenticated Local (Individual, Staff)
  • e.g., staff home pages (which may be related to
    official role or may not)
  • Unauthenticated Local (Individual, Student)
  • e.g. student home pages (which may be connected
    with study or may not)
  • All types of information on an "Associated
    Organisation" sub-site
  • e.g,. HUBS, BCS branch

23
3. Establish Degree of Centralisation
  • Locus Centralised or Decentralised
  • Control Autonomous or Restricted
  • Gives 4 main models
  • 1. Centralised Restricted
  • 2. Centralised Autonomous
  • 3. Decentralised Restricted
  • 4. Decentralised Autonomous
  • Ref Samuel Hinton, From Home Page to Home
    Site, a paper presented at WWW7 - see
    http//www.anu.edu.au/e951611/www7/37.html
  • Information should be managed as close to its
    source as possible?
  • Requires strong definition and co-ordination of
    information strategy
  • Requires local web expertise

24
Decentralisation
  • Some sort of decentralised model is most likely
  • fully centralised would be utterly impractical
  • Raises issues of
  • control
  • how to enforce corporate policies
  • academic institutions are notorious for autonomy
  • integrity
  • how to ensure consistent information
  • e.g.,local copies of corporate data
  • security
  • who is authorised to edit documents
  • technology
  • system integration and accessibility

25
Is it Internal or External?
  • The temptation was (is?) to put everything on the
    web
  • simply because you can (not a good reason)
  • Not everything is fit for public consumption
  • Some information is merely irrelevant
  • use of fire extinguishers
  • Some information may be confidential
  • minutes of meetings
  • Some information may be downright embarrassing
  • internal reports about departmental inefficiency
  • Need for split into Internet and intranet
    websites
  • This requires you to know what information you
    have, who provides it and who wants it - need for
    an audit

26
Development of Multiple Websites
  • External-facing
  • For Visitors
  • General information
  • For Prospective Students
  • Prospectuses, local information
  • Internal-facing
  • For Existing Students
  • Course materials, regulations, results
  • For Staff
  • Administrative information, procedures
  • Technically possible to filter some users at
    point of access
  • IP masks for known groups
  • staff, students, etc

27
4. Assign Information Management Responsibilities
  • Is there an existing system?
  • e.g., ISO 9000 (BS5750) procedures
  • Central co-ordination and control
  • Planning overall information resources
  • e.g., organisational data model
  • formulating policies (security, access, etc)
  • How much does it actually do (versus just
    co-ordinate)
  • More autonomy at local level more control at
    the centre
  • Local management and enactment
  • Defining, providing maintaining information
  • Ensuring compliance with central policies (e.g.
    security, style)
  • Identifying changes in requirements and practices

28
5. Technical Infrastructure (TI) Issues
  • The Web adds a layer on top of existing TI
  • Unifying shell or wrapper over heterogeneous TI.
  • Can help remove problems - but can add them too
  • All requires additional resources and management
  • Need to maintain underlying systems remains
  • But use of Web may show need to consolidate them
  • Danger of uncontrolled local technical
    developments
  • The weeds taking over the garden (James Martin)
  • e.g., browser-specific resources, plug-ins, etc
  • Is the required client technology widespread?
  • Core TP systems will remain (e.g.,finance,
    records),
  • but the Web can simplify access to them
  • Subsidiary system elements may still required to
    meet specific local needs

29
6. System Integration Issues
  • Institutions will already have multiple systems
  • Proprietary/commercial and bespoke in-house
  • Enterprise-wide and local
  • What are the available interfaces?
  • ODBC, DCOM, ActiveX, Java-based ...
  • How mature and stable are the standards?
  • Where does the integration occur?
  • Before the server?
  • some sort of middleware
  • At the server?
  • built-in/add-on interfaces or CGI
  • At the client?
  • Java or ActiveX ... or something else
  • Enforcement of standards?

30
Who runs your website?
  • Which department?
  • Computer Centre/IT Services department?
  • Because its technical
  • Marketing, Publicity or Media department?
  • Because its public-facing
  • Registry (or equivalent)
  • Because its a major data resource
  • Staffing
  • Webmaster - historically technically-based
  • A dedicated multi-skilled team?
  • High-level involvement
  • Both corporately and departmentally
  • Often little understanding of the issues
  • Design and Technical
  • Usually inadequate resource allocation and
    timescales

31
Case Study 1Media and Publicity Services
  • A traditional marketing department
  • Responsible for
  • Prospectus and corporate advertising
  • Press relationships
  • Took over control of website at early stage
  • Commissioned first web-based prospectus
  • Relinquished control of website
  • Because no extra funding available for the extra
    work
  • But actively involved in developing content
  • Aim of databased information sources - currently
    heavily reliant on manual intervention
  • No specific web related posts
  • but Web awareness now a short-listing criterion

32
Case Study 1Media and Publicity Services
  • Web seen as a central tool
  • but other channels remain key (e.g. hard copy)
  • ironically, production of printed media likely to
    increase as result of web originated requests
  • Web initially seen as marketing dream
  • 24 hrs, global, always current, local production
    costs
  • Cost of producing web material became a barrier
  • Conventional media now points to web resources
  • increased expectations of what is available
  • Email direct from web pages opens up
    institution
  • Not keen on policing content of entire site
  • Many rogue pages not widely seen anyway

33
Case Study 2The Registry Intranet
  • Began as a small proof-of-concept project
  • A demonstrator to provide (limited) central
    information
  • e.g. exam and teaching timetables
  • An administration server
  • accessed by simply typing admin into browser
  • Once people saw what was possible..
  • Requests to provide information on others behalf
  • Spawned other departmental intranet servers
  • The information is all there
  • Making it available is technically easy
  • But it takes time, needs staff (and costs money)
  • Very successful
  • But not yet strategic - still a local
    initiative

34
Case Study 3Student Information Project
  • University-wide initiative
  • Not Website specific
  • But the Website highlights issues of provision
  • Major questions
  • What information do we provide to students?
  • What information should we provide?
  • How should we provide it?
  • Student life-cycle perspective
  • Horizontal rather than vertical division
  • Integrates across internal boundaries (like the
    web?)
  • Avoids imposition of internal structures on
    students
  • Students still want hard-copy information
