Introduction
London Help Forum (LHF) currently wants to develop a number of legal advice
centres throughout London area. As the first step, the CEO of LHF would collaborate with Leyton
Community Legal Centre (LCLC). In order to collaborate with LCLC, there would be required to
develop new information systems.
Throughout this report, we are going to describe the requirement analysis for the
new system. Rich Picture and Use Case modelling would be used in requirement analysis. After
that, we would critique the rich picture and the use case.

COMP- 1645 Page 8
A 1.2 CATWOE Analysis
CATWOE Analysis was defined by Peter Checkland as part of Soft Systems
Methodology (SSM).CATWOE analysis is about what the business is trying to achieve and helps
all the people, processes and external factors involved in the information system that is being
analysed. CATWOE analysis can be used to produce Root Definitions. (Ref:
http://bpmgeek.com/blog/what-catwoe-analysis )
In this part, we are going to elaborate some CATWOE analysis for the proposed e-legal
system.
C- Customers/Clients
Customers or clients are stakeholders who are on the receiving end of whatever
the system does. In the system, Leyton area residents who need legally help or information from
LCLC are customers orclients. We would call them “Legal aid needers”. They are on the
receiving end of the system and will get the benefit or suffer from the system.
Due to the present manual system of LCLC, some of legal aid needers do not get
fair share of appointments sometimes. There are a lot of extra paper work and no effectiveness.
A number of action forms of the legal aid needers are missing. By developing new eLegal
system, these problems might be solved easily though some of the staffs in LCLC (for example –
Hao Lee) do not want to use the computer system.
A- Actors/ Agents
These are people involved for the main activities in the new system. Actors in the
system would be admin staffs (for example- Hao Lee) and other operational staffs (for example-
Lan Wei, KPI Support Officer). They are responsible to operate the system.
Present manual system has no data security and some data are losing. It is very
difficult to collect information for report. The new eLegal system might surpass some
difficulties. However, people who are not familiar with computer systems might resist the new
system.
T- Transformation
Transformation is the changes that the system will bring about.
 How the systems convert inputs into the outputs?
According to the case study, the inputs might be “legal issues” of the legal aid
needers. The e-legal system has to transform these inputs into outputs. The outputs might be
“KPI reports” and “satisfaction of legal aid needers”.

COMP- 1645 Page 9
W- Weltanschaung
The world view is that analyzing on other impacts that could be affected to the
system. The world view is generally the view of stakeholders who do not directly involved in the
system, but can affect the system. Funders of LHF are stakeholders of this kind.
Owner
These are people who own the company. They are interested in developing new
system and its impacts. They are also worry about other stakeholders who could make a claim
for ownership or part of ownership. In the proposed eLegal system, the owners might be
Matthew Lord, CEO of LHF and Jasmine Le Blanc, Director of LCLC.
Environment
These are external impacts which are needed to be aware. The demands of
political, legal, technological and others are needed to analyze by the LHF every day.
For example deals with LHF, the government could change the country's rules
and laws. There would be emerged new competitor charity in the region.
(Ref: http://karvediat.blogspot.com/2010/10/root-definition-catwoe-model-ethics.html)
A2. Discussion for Complete London Help Forum Environment
A 2.1 People or Stakeholders in the LHF Environment
Stakeholders are something that takes part in the organization process. A
stakeholder might be a person or process. A lot of stakeholders could involve within London
Help Forum (LHF) processes directly or indirectly. In this part, we will find out the stakeholders
according to the rich picture.
Each stakeholders, their tasks, roles and responsibilities are displayed. All
stakeholders are taken out based on the above rich picture.
(1) Chief Executive Officer (Matthew Lord)
CEO of LHF, Matthew Lord is working along with admin team, finance services,
admin services, member charity services, human resources, marketing and IT development. He is
the highest responsible role within LHF.

COMP- 1645 Page 10
(2) IT Director (Julieanne Black)
Julieanne Black is the IT director of LHF. She is responsible to develop and
maintain the computer systems of LHF such as eLHF system. In developing eLegal system, she
would involve in key role.
(3) Head of Member Charity Services (Linda Wong)
Linda Wong is the in charge of all member charities. She is responsible to work
with them all the time. She is responsible to make a monthly meeting with directors of member
charities.
(4) Finance Director (Patience Mbewe)
He is a responsible person to report to main funders. He has some conflict with IT
director at the moment.
(5) KPI Support Officer (Lan Wei)
He is responsible to collect data deal with key performance indicators (KPI). He
needs data from all the advice centres daily. He transforms the data into reports on time to
present funders. He would be one of the key stakeholders in new eLegal system.
(6) Member Charities
Member charities are responsible to deliver the actual advice and support services
to the community advice centres. On the other hand, they need to send report to LHF head office.
The member charities must agree the LHF framework otherwise they would not be funded.
(7) Community Advice Centres
Twenty community advice centres across London are providing actual advice and
support services to London residents. The centres are working along with the advices of member
charities.

COMP- 1645 Page 11
(8)Director of Leyton Community Legal Centre (Jasmine Le Blanc)
Jasmine Le Blanc is the director of LCLC. She recruits new solicitors. This may
include interviewing new solicitors, asking for references and proof of qualifications. And, she
checks reports from Hao Lee and works out how many legal aid needers they have been
working.
(9) Administrative Officers (Hao Lee)
Administrative officers of LCLC would be one of the key stakeholders in new
eLegal system. They are responsible to recruit volunteer staffs and add new legal aid needers. If
the legal aid needers have problems that pro bono solicitors can assist, they make appointments
at appropriate time. They make report for Jasmine to check.
(10) Pro bono Solicitors
Pro bono solicitors are a kind of volunteers in LCLC. Their responsibility is to
consult legal aid needers. They have to create action forms after consulting with legal aid
needers. After a legal aid needer had been consulted, they have to produce the result of
consultation.
(11) Admin Volunteers
LCLC is a non-profit organisation. It cannot hire a lot of employees. Therefore,
admin volunteers are important for the charity.
A 2.2 Organisational Structure
Organisational Structure is about how an organisation is physically or logically
structured. We can understand the conflicts and different culture based on the organisational
structure. In this part, we will critically discuss about how many different organisational
structures does the LHF environment has, how they organise and how they are working.

COMP- 1645 Page 12
A 2.2.1 Organisational Structure of LHF Environment
The LHF environment is generally organised in four different structures. They are
chosen based on the rich picture shown above. They are-
(1) LHF Head Office
(4) LCLC Office
(1) LHF Head Office
LHF head office is currently controlled by CEO, Matthew Lord. The Senior
Executive Group which composed of CEO and his admin team makes the strategic decisions.
The office has a number of full-time and part-time employees. The LHF head office gives advice
services to London residents via twenty community advice centres.
There are five different charities which are known as members under LHF head
office. Each charity has a director and employees. The director of the charity is required to attend
monthly meeting held at the LHF head office.
There are twenty community advice centres across London which takes financial
support from the LHF head office. But the actual advice and support services are taken from
member charities. Each advice centre is composed of a centre manager, employees and
volunteers.

COMP- 1645 Page 13
(4) LCLC Office
The LCLC Office was founded by its CEO, Jasmine. There are currently two full-
time administrators, three volunteer administrators and four pro bono solicitors are working.
LCLC is going to become a member charity of LHF.
A2.3 Systems that Need to Be Built
Current eLHF system did not reach the user requirements. Some of member
charities stopped using eLHF system and developed their own in-house systems to collect data.
Many of other member charities are also willing to build their own in-house computer systems
otherwise they would leave from LHF. Therefore, LHF head office is in trouble and might have
to allow the member charities to use their own systems. If this so, LHF might need to create a
computer system that collaborates with different systems from member charities.
According to the above conflicts, interviews and the rich picture, a kind of system
called Management Information System (MIS) might be required to be built. This is because
the MIS system can produce reports for LHF head office based on data extracted from the in-
house system of member charity.Executive Information Systems (EIS), which is a kind of MIS
systems, is a reporting tool that can provide quick access to summarized reports from all member
charities. These regularly scheduled reports can be sent to eLHF database immediately.
(Ref: http://wikipedia.org/wiki/Management_information_system)
A2.4 Key Issues and Areas of Conflict Affecting the Environment
Some of the stakeholders in LHF environment are against to the eLegal system.
 Head of member charities thinks that there are not enough staffs to handle the new
member charity. And she believes that eLegal will not be effective and difficult to use.
 Finance Director mentions that there is not enough finance for the new member charity.
 KPI support officer (Lan Wei) needs data from member charities in time. And some data
are difficult to collect because of different formats.
Some of the staffs and volunteers in LCLC do not welcome the new computerised system.
 Administrative staffs (for example- Hao Lee) are not familiar with computer systems and
would quit if they were forced to learn the new eLegal system.

COMP- 1645 Page 14
 Volunteers are not willing to take part in the new eLegal system. For example, David
Mwambu, the pro bono solicitor, said that if the working procedure or culture changed
too much then he would think about leaving.
The IT director does not know about requirement gathering from user.
 Julieanne Black, the IT director, said that she thought interviewing the staff at the Leyton
Community Legal Centre is a waste of time. She knew what information we need to
collect and what processes they need to follow.
 According to her, she does not know how user requirements are important. She is
focusing only on hard approaches.
 My opinion is that former systems such as eHomeless and eDebt systems did not meet
the user needs because she did not try to understand what user really needs.
A2.5 Issues that Individual People Discussed
Each stakeholder has worries deal with implementing eLegal system. Here, we
will critically describe the issues that are discussed by the key actor who will use eLegal system
directly.
 Administrative staff (Hao Lee) discussed that he is technophobe. And he does not want to
learn how to use new eLegal system. But at the same time, the manual process makes him
extra paper work with no effectiveness.
 Director of LCLC (Jasmine)has a problem that she has no time to devote to the legal
centre. And she does not want her staff to go through the LHF induction course. This is
because LCLC has their owned induction course.
 Pro bono Solicitors don’t want to involve with a lot of new processes. If the working
culture changes too much, some of the solicitors would leave LCLC.
A2.6 what is Organisational Culture?
Organisational Culture is that a specific working style or behaviour of an
organisation. It is mostly depend on environmental factors. Because of the different working
styles and background of the organisations, each culture of organisation cannot be the same.

COMP- 1645 Page 15
A2.6.1 Different Cultures and Sub-Cultures in the Environment
 London Help Forum has five member charities. Each member charity has different
working culture.
 Different funders of LHF would have different perspectives in funding.
 LHF might want LCLC to use new eLegal system. But admin staff (Hao Lee) do not
want to use new computer system.
 Director of LCLC (Jasmine) do not want her staffs and volunteers to take LHF induction
course. But LHF head office thinks the induction course of LCLC is not enough.In fact,
each induction course of the charities will be different.
 LHF head office wants LCLC to use a computer system but LCLC prefers to use manual
system.
A2.7 High Level Processes in the Environment
Produce result of consultation is a high level process of LCLC. To produce
consultation result, a pro bono solicitor must make appointment with a legal aid needer and then
discuss about legal issue. Once the meeting with the legal aid needer is finished, the solicitor
writes an action form. If the legal aid needer request, another appointment with the solicitor will
be scheduled. After all, the solicitor has to combine all the action forms together and finally
produce the result of consultation to solve legal issue of the legal aid needer.
Produce KPI reportmight also be a high level process. To produce a KPI report,
a number of data have to be collected. And responsible staff needs to compare the actual result
with the expected results.
In fact, developing new eLegal system itself is the high level process of LHF head
office.
A2.8 Sources of Scrutiny in the Environment
The followings are the main scrutiny of LHF environment.
 Funders of LHF might be scrutiny because the funders will check the KPI results, the
performance of LHF and its member charities.
 Local Government Authorities are also need to be concerned as they might change the
rules and regulations and watch LHF follow or not the regulations.
 Competitor Charities might also find the weaknesses and threats of LHF. And they
compete with LHF in order to get funds from funders and government organisations.

COMP- 1645 Page 23
B3. Justifying processes to arrive final documented use case diagram
B3.1 Choosing Key Actors for Use Case Diagram and Their Key Roles
According to case study, the new system that is required to be built is for LCLC.
Therefore, the stakeholders from LCLC are more focused to be actors than stakeholders from
LHF. Generally, the stakeholders from LHF might not be the key actors in the new eLegal
Management Information System.
Choosing Primary Actors
Administrative Staff (Hao Lee)
The person who is highest responsible in the system would be Administrative
Staff. Administrative staff is responsible to work between director, pro bono solicitors and the
legal aid needers. Without Administrative staff, the transactions between director, pro bono
solicitors and the legal aid needers would be difficult. Therefore, they are chosen as one of the
key actors in the use case diagram.
The role of administrative staff in the system is very critical. This is because all of
data collecting transactions such as “Record New Volunteer Staff” and “Record New Legal Aid
Needer” would be done by administrative staff. And the administrative staff is responsible for
the other high level processes such as “Make Appointment” and “Report Legal Aid Needer
Files”.
Pro Bono Solicitor
The pro bono solicitors are one of the responsible actors from LCLC. According
to the interviews, they should be actors because they create “action” forms and “result of
consultation” for the legal aid needers. Without pro bono solicitors, the major services of LCLC
would decline.
They are key to the system because only the pro bono solicitors knowhow to solve
the legal issues. The critical transactions such as “Produce Action Form” and “Produce
Consultation Result” will be done only by the pro bono solicitors.
KPI Support Officer (Lan Wei)
Though KPI Support Officer is a stakeholder from LHF head office, he will be
one of the key actors in the eLegal Management Information System. This is because the KPI
Support Officer is responsible to produce KPI reports for LCLC.

COMP- 1645 Page 24
The main purpose of eLegal Management Information System is to produce
accurate KPI reports, and therefore KPI Support Officer is very important since he is responsible
to produce KPI reports.
Choosing Secondary Actors
Director (Jasmine)
Jasmine Le Blanc, director of LCLC, was chosen as a secondary actor. This is
because according to the scenario, she is the most responsible person to check the reports that
administrative staffs send.
Legal Aid Needers’ files are required to report to director by administrative staffs.
Director role in the system is very important since she is responsible to check how many legal
aid needers they have been working with and how successful the service has been.
B 3.2 Identifying Key Activities to Include in Chosen Primary Scenario
The primary scenario for “Make Appointment” is chosen to explain how the
key activities are identified to include in it. According to the scenario, there would be three key
activities to complete this transaction. They are –
1. Checking legal aid needer information
2. Checking first or second appointment
3. Making appointment at an appropriate time
1. Checking Legal Aid Needer Information
When a legal aid needer comes to request for an appointment, administrative staff
must check the information of that legal aid needer. Otherwise, the administrative staff would not
know the legal aid needer has registered or not. Therefore, “Checking legal aid needer
information” was included as a key activity in the primary scenario.
2. Checking first or second appointment
After checking legal aid needer information, the administrative staff needs to
check whether the appointment isfirst time or second time. This is because if the appointment is

COMP- 1645 Page 25
second time, the administrative staff requires to ask the reason for second appointment. Without
this transaction, administrative staff would not know the appointment is first time appointment or
second time appointment.
3. Making appointment at an appropriate time
The administrative staff needs to check the free time of a pro bono solicitor for
the appointment. It is a key activity because the administrative staff could not negotiate the
appointment time without checking the free time of a pro bono solicitor.
“Make Appointment” transaction could be done by doing the above three main
key activities. The key activities were identified from actor point of view (i.e. administrative
staff point of view) and assumed every transaction is going right. To process this use case, the
information such as records of pro bono solicitors and records of legal aid needers would be
needed.
B 3.3 Identifying Secondary Scenarios
The alternative ways or secondary scenarios were described for two use cases,
“Make Appointment” and “Produce Action Form”. Generally, secondary scenarios were
identified for all the possible different conditions. Secondary scenarios are similar with “If...Else
If” condition in programming languages.
The followings are examples of how we identified the secondary scenarios.
Secondary scenarios for use case “Make Appointment”-
Checking the legal aid needer has registered or not becomes two different possible
conditions. If the legal aid needer has not registered yet, he/she needs to register first. Otherwise,
the legal aid needer could not make appointment with a pro bono solicitor.
Checking the legal aid needer files to know first or second appointment becomes
to evolve secondary scenario. If the legal aid needer is requesting for the second appointment,
the administrative staff needs to ask the reason for the appointment.

COMP- 1645 Page 26
B 3.4 Assumptions for the System
As the system is focused for LCLC, the perspectives and cultures of stakeholders
from LCLC are very important. Some stakeholders from LHF head office, who are working
together with LCLC, such as KPI support officer and CEO, also take part in the system.
Therefore, we need to ask some questions to these actors to get necessary information.
B 3.4.1 Questions that need to be asked for the system
LHF head office
Chief Executive (Matthew Lord)
 Do other stakeholders in the organisation advocate to collaborate with LCLC?
 What specific data are needed to produce KPI report? (for example: number of legal aid
needers per week, number of successful consultation per week)

Part C – Critique of Use Cases and Rich Pictures
C1. Differences between Use Case and Rich Picture
C1.1 Rich Picture
 Rich picture is a part of soft system methodology.
 In drawing rich picture diagram, there are no specific rules and restrictions. We can use
any graphical representations.
 The main purpose of drawing rich picture is to know about issues (for example- issues in
collecting data from member charities), conflicts (i.e. different opinions of stakeholders)
and processes (which stakeholders do for what transactions? But does not include how
they do these processes.).
 Rich picture of LHF environment shows the social, moral, ethical and human aspects.
 Rich picture of LHF is about understanding the whole environment of LHF (i.e. LHF
head office, member charities and LCLC).
 All the stakeholders (for example- IT director of LHF, Finance director of LHF) are
included.
 Problem situation is expressed in the rich picture but unstructured.
C1.2 Use Case Diagram
 Use case diagram is a part of hard approach.
 In drawing use case diagram, there are rules and formats such as system boundary, use
case, actors and relations.
 The main purpose of use case diagram is to know about key actors (for example-
administrative staff (Hao Lee), key processes (for example- produce KPI report) and
relationship between them.
 Use case diagram shows the functionality (for example – make appointment), data
requirements (for example- lists of volunteer staff, lists of legal aid needers) and systems
behaviour.
 Unlike with rich picture diagram, use case diagram is focusing only on the elegal
management information system for LCLC.
 Only the key actors who process the e-legal management information system (for
example- administrative staffs of LCLC, KPI support officer) are included.
 Use case diagram shows the steps to solve the problems which were expressed in the rich
picture diagram.

C2. Helpfulness of Rich Picture and Use Case in Requirement Analysis
C2.1 Rich Picture
Rich picture diagram of LHF helps us to understand the current situations and
problems of the whole organisation. As an analyst, we can perceive the organisation structure
and cultures of LHF by using rich picture diagram. We could also identify which systems need to
be built. Moreover, we can understand the different views or opinions of the stakeholders in LHF
environment.
Issues could be identified by looking “crossed swords” in the rich picture.
Conflicts and problems could be found by identifying “though bubbles” of stakeholders and the
processes could be identified by looking at “relationship lines”.
Without rich picture, the new e-legal management information system would be
inflexible for users to use. The new system might not meet the needs of the users. As a result, the
users will not satisfy to use the system.

C2.2 Use Case Diagram
Use case diagram for e-legal management information system helps us to know
the key actors, key processes and the relationship between them. Business use case
descriptions or primary scenarios for each business use case show us how the key actors do the
key processes.Secondary scenarios show us to notify things that can go wrong in a process.
Without use case diagram conceptual model, we would not know how to develop
the new e-legal management information system and what the current processes are. In
conclusion, both of the conceptual models are very useful in the requirement analysis stage.
C3. Connection between Rich Picture and Use Case
There are a lot of connections between rich picture and use case. Generally, a rich
picture shows the current situations and problems. Use case diagram shows the steps to solve the
problems which were expressed in the rich picture diagram. For example, use case diagram for e-
legal management information system shows the steps to solve the problems in LCLC which
were expressed in the rich picture.

C3.1 Stakeholders to Actors
Some of the key stakeholders involved in the rich picture are transformed into
actors in the use case diagram (for example- administrative staff (Hao Lee), Pro bono solicitor
and KPI support officer (Lan Wei)). Actors in the use case diagram were chosen based on the
problem scope which was described in the rich picture diagram. For example- administrative
staff (Hao Lee) was described as a stakeholder in the rich picture diagram and also involved in
the use case diagram as a key actor.
C3.2 Processes to Use Cases
The processes such as “Make Appointment” and “Produce Action Form” involved
in the rich picture diagram are transformed into use cases in the use case diagram.Therefore, we
can assume some key processes shown in the rich picture might be use cases in the use case
diagram. It might depend on problem scope and what system will be built.

C3.3 Problem Scope to System Boundary
According to the case study, the new system is focused for LCLC rather than
LHF. Therefore, the problem scope was assumed to be LCLC. The LCLC problem scope which
was described in the rich picture was transformed into the system boundary of the new e-legal
management information system in the use case diagram.

Conclusion
In Part A, requirement analysis such as stakeholders, organisational structure,
conflicts, issues and processes are identified using rich picture. We also analysed the problem
scope, high level processes and the sources of scrutiny. Based on the problem scope, we
discussed to develop a new information systems call e-legal management information system.
Throughout Part B, we identified the requirement analysis by using use case
diagram. We discussed the key actors, the key processes and the relationship between them. We
also analysed the business use case description or primary scenario for each use case.
As Part C, we described the differences between rich picture and use case diagram
based on our experience in LHF environment. We also discuss how these approaches help us in
requirement analysis stage. Finally, we provided the connection between rich picture and use
case diagram.
