The document describes several methods for collecting information during the initial systems analysis stage: observation, examining documents, questionnaires, and interviews. Observation allows analysts to see real work processes and how data flows. Examining documents provides information on what documents are used currently. Questionnaires can gather data from many people but have low response rates. Interviews are the most important technique as they allow analysts to clarify any unclear answers. Collecting information from multiple sources helps analysts understand current systems and user needs.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

2. Systems Analysis
The
process of
investigation of a system’s
operation with a view to
changing it to new
requirements or improving
its current working.
3. NEED FOR SYSTEMS ANALYSIS
Systems analysis will identify
1. outputs and processing needed.
2. data required to provide this processing and
output.
3. role of people in the process.
4. security aspects to ensure the efficient
continuation of the business.
5. costs of providing the system.
4. THE ROLE OF THE SYSTEMS ANALYST
Liaison with senior management and
the computer manager on the need
for new/improved systems.
Begin the implementation by
convening a meeting of the new
system designers.
Investigate aspects of the business
and produce a Feasibility Report
Consult with the users who are using
the current system.
Order Hardware and any
structural/electrical wiring changes
needed to buildings.
Supervise testing of new programs. User
training with programs.
Design all aspects of a new system.
Report on developments to the
board and identify any likely
changes needed/problems
discovered as a result of
investigations. Produce a systems
specification.
Supervise completion of
documentation.
Acceptance tests. Changeover. Handover
Monitoring of existing systems. Regular
reviews to see if changes are needed.
Supervise maintenance and inclusion
of new requirements.
5. INVOLVEMENT OF OTHER STAFF
1. Departmental managers & board. Initiate new systems.
2. Departmental managers. Brief systems analyst on departmental needs, identify
key processes, documents and key workers.
3. Users. Assist manager and systems analyst in providing information about
current systems . Identify particular individual needs of a new system.
Undertake training from initial outlines of the new system to specific training
on using it.
4. IT Technical staff. Installing and testing new equipment.
5. Development Programmers. Initial briefing about the whole new system, oneto-one briefing about individuals own designated tasks. Keep systems analyst
updated on progress and problems. Assist with testing of the new system.

6. Maintenance Programmer(s). Become familiar with all programs including one
not written by the programmer. Perform changes as required as a priority.
7.
1 Observation
The aim of observation
is to find out what
actually happens, not
what the workers think
observers expect to
see.
The point of observation is
to see who does what in an
organisation and what
information they do it with.
By simply watching people
working it is also fairly
straightforward to watch
how data flow around a
system. Observers have to
be careful of the
Hawthorne effect. This is
where workers modify their
behaviour because they
know they are being
watched.
8. Observation
Advantages
Disadvantages
Data gathered can be very
reliable
Can see exactly what is
being done in complex
tasks
Relatively inexpensive
compared with other
techniques
Can do work
measurements
People may perform
differently when being
observed
Work observed may not be
representative of normal
conditions
Timing can be inconvenient
Interruptions
Some tasks not always
performed the same way
May observe wrong way of
doing things
9. Observation Guidelines
Determine the who, what, where, when, why, and how
of the observation.
Obtain permission from appropriate supervisors.
Inform those who will be observed of the purpose of
the observation.
Keep a low profile.
Take notes.
Review observation notes with appropriate individuals.
Don't interrupt the individuals at work.
Don't focus heavily on trivial activities.
Don't make assumptions.
10. 2 Examination of
documents
All documents which are
used within a system need
to be examined. These will
be eventually duplicated
or replaced with
alternative versions or
even discarded in the
new system.
11. The types of document which
need to be examined are:
Data
capture forms
System
documentation
Business
reports
Invoices
Bills
Letters
etc.
12. 3 Questionnaires
The use of questionnaires is a
very popular method of fact
finding. A great deal of time
is spent on preparing
questionnaires in order that
the right type of question is
asked in order that the most
relevant information is
gathered.
Free-format questionnaire – a
questionnaire designed to
offer the respondent
greater latitude in the
answer. A question is
asked, and the respondent
records the answer in the
space provided after the
question.
Fixed-format questionnaire – a
questionnaire containing
questions that require
selecting an answer from
predefined available
responses.
13. Questionnaires
Advantages
Often can be answered
quickly
Disadvantages
Return rate is often low
No guarantee that an
individual will answer all
questions
People can complete at
their convenience
Relatively inexpensive way
to gather data from a large
number
No opportunity to reword or
explain misunderstood
questions
Allow for anonymity
Responses can be
tabulated quickly
Cannot observe body
language
Difficult to prepare
14. Types of Fixed-Format
Questions
• Multiple-choice questions
• Rating questions
• Ranking questions
Rank the following transactions according to the amount of
time you spend processing them.
___ % new customer orders
___ % order cancellations The implementation of quality discounts
___ % order modifications would cause an increase in customer
orders.
___ % payments
___ Strongly agree
___ Agree
Is the current accounts
___ No opinion
receivable report that you
___ Disagree
receive useful?
___ Strongly disagree ___ Yes
15. Developing a Questionnaire
1.
Determine what facts and opinions must be
collected and from whom you should get them.
2.
Based on the facts and opinions sought, determine
whether free- or fixed-format questions will
produce the best answers.
3.
Write the questions.
4.
Test the questions on a small sample of
respondents.
5.
Duplicate and distribute the questionnaire.
16.
Objective:
Find facts
Verify facts
4 Interviews
Clarify facts
Generate enthusiasm
An interview can take
more time to organise
and it is extremely
difficult to repeat so it
is vital that the
questions asked are
the right ones.
Get the end-user involved
Identify requirements
Solicit ideas and opinions
The personal interview is generally
recognized as the most important and
most often used fact-finding technique.
17. Types of Interviews and
Questions
Unstructured interview –conducted with only a general
goal or subject in mind and with few, if any, specific
questions. The interviewer counts on the interviewee
to provide a framework and direct the
conversation.
Structured interview –interviewer has a specific set of
questions to ask of the interviewee.
Open-ended question – question that allows the
interviewee to respond in any way.
Closed-ended question – a question that restricts
answers to either specific choices or short, direct
responses.
18. Interviews
Advantages
Give analyst opportunity
to motivate interviewee
to respond freely and
openly
Allow analyst to probe
for more feedback
Permit analyst to adapt
or reword questions for
each individual
Can observe nonverbal
communication
Disadvantages
Time-consuming
Success highly
dependent on analyst's
human relations skills
May be impractical due
to location of
interviewees
21. A Fact-Finding Strategy
1.
Learn from existing documents, forms, reports, and
files.
2.
If appropriate, observe the system in action.
3.
Given all the facts that already collected, design and
distribute questionnaires to clear up things that aren’t
fully understood.
4.
Conduct interviews (or group work sessions).
5.
(Optional). Build discovery prototypes for any
functional requirements that are not understood or for
requirements that need to be validated.
6.
Follow up to verify facts.
