A2.1    Identification of the key actors in the environment

The rich picture is based on the key factors identified from the cases study. I base the identification of the main factors on CATOWE system of analyzing organization. CATOWE stands for. In examining an organization the CATOWE system is significant for expressing a problem by demystifying all the situational and permanent factors involved.  In this regard I consider CATOWE a description of the human activities and situation involve tin the AgeCare environment. CATOWE is an acronym standing for Customer, Actor, Transformation, World view and Environment. This is a body of five factors that make up of an organization such as AgeCare. The elements identified using CATOWE are listed bellow

Customer

The customers are the beneficiaries of the activities of the organization. The main beneficiaries are the elderly people whose needs are the main inspiration for the existence. Supermarket the support the program could also pass for customer since the elderly people supported by the program purchase their good thus boosting their revenue.

Actors

Actors are the individual behind the running of the program. Indentify actors was as easy as indentifying the customers. The actors in this program the employees, both permanent employees and the volunteers who offer service at their convenience.  The other actors are the fanciers such social service and supermarkets which fund the activities such as paying for the good bough by the elderly, fueling their vehicle and financing management operations among others.

Transformation

Transformation on the other hand is a process of change. The transformation in Agacare environment is a change in its operation model.  The management of the organization is inefficient, poor record keeping, poor accountability, lack of proper coordination between departments, disagreements and the need to embrace information technology.

World View

AgeCare is based on a world view that there is need to provide the elderly people with the necessary or basic service to enable them to have a fulfilling life.

Environment

The AgeCare environment is characterized by numerous projects targeting various aspects of the aged in the society.   The environment is customers who are the elderly people served by the projects, and actors who are the people involved in the financing and implementation of the projects.

A2.2    What led you to choose the key issues and areas of conflict affecting the environment that you have included in your diagram?

The choice of the key issues and areas of conflict affecting the AgeCare environment included in the diagram we chosen because of their central role in the presenting a summary of what AgeCare is all about. My aim was to symbolically present what AgeCare stands for, its activities and the people and organizations involved the activities of AgeCare. The diagram further represents the served in a symbolic manner.  The choice was base on my belief that picture can be used as symbols to represent or develop a concrete meaning for perceive realities. To understand my perspective one must first agree that picture are symbols of reality and what take place in every organization is symbolic. All situation, factors and process are having indisputable symbolic values. The perception of these values is like reading a script of information concerning the organization.

Base on these views, I made the selection of the issues depicted in the picture to give observers a summery description of the relationships between player, actors, customers and processes in the AgeCare environment.   Observers can gain knowledge on the organization structure of AgeCare by simply studying the picture.

A2.3.   The main focus of the environment shown in your picture

In general, the main focus of the environment shown in the picture is the stakeholder and organization component of the AgeCare environment. To a specific level, the picture depicts the organization processes initiated by the stakeholders through the organization structure of the firm. An organization exists due to its strake holder and their activities. The stakeholders therefore, make an organization what it is by being responsible for it performance and dictating its services. This picture show AgeCare stakeholders, their organization structure, interactions and processes involved in delivering the service the organization was designed to deliver.

A2.4    Where does the control of systems, data and processing lie in the environment as shown in your picture?

Control systems, data and processing lie in almost every aspect of the environment shown in the picture. Every process involved in value delivery by the organization.  However, most of the control lies in the management which can be considered senior of executive management.

The senior management in the organization is the source of all the activities conducted by the organization. The executives initiate the activities and projects the organization undertakes. They design these programs and allocate resources for the realization of the programs goals. It is the executive officers that hire all employees including volunteers.

The executive office also monitors the activities of the sub center that are dispersed in other regions in the south of England.  It coordinates the finances and labor allocated to his centers.  It hold the centers accountable for the resources the receive form the executive office.

There is also a sphere of control from the financiers who donate most of the funds for various projects. These donors normally insist getting copies of reports indicating how project funds were utilized. Accountability is the main quality that the financiers insist one. Many financiers shy away from funding future programs when they notice discrepancies or fail to get proper accountability.

Section B – Requirements Analysis using Use Case modelling

The Green Drive project has been selected for the pilot project on the introduction of Information Technology systems in the AgeCare organisation. All the information about the Green Drive has been provided in by the AgeCare case stud in Appendix A.  In this section I am going to analyse the Greed Drive project using Use Case Modelling. Use cases are scenarios which describe the channels by which an actor achieve a specific goal. In this regard, a use case model will consist of all the actors and use cases involved in realization of a common objective.

• Draw a use case diagram for the system clearly identifying the actors involved.

            B1.1    A primary scenario for each use of the system

Scenario 1

Driver (actor) → System →Authentication → Access → Results (Duty plan, designate route and stops, bus assigned)

Scenario 2

Doris (Actor) → System → Authentication → Access →Results (Time bus returned, problems experienced, amount of fuel refills, receipt number)

Client → System→ Authentication → Access →Results (route of the day, time of collection, time of return)

B1.2     A secondary scenario for each use of the system

Driver (actor) → System →Authentication failure→ Access denied →suggestion/redirection

Scenario 2

Doris (Actor) → System → Authentication failure→ Access denied →suggestion/redirection Scenario 3

Client → System→ Authentication failure→ Access denied →suggestion/redirection

• Describe and justify the process that you followed to arrive at the final use case diagram. In describing this process, answer the following four questions:

B2.1.   Why did you choose the actors you did and why are they key to the system?

I chose the actors in the use case model above because they are the main cause of action and activities engage in to realize the objectives of the project. Total of six actors are in this process. These include Clare Graham, Doris Smith, Drivers, the clients, social services, and supermarket. The contribution by each of the above actors leads to realization of shopping trips for the elderly people on the areas served by the project.

B2.2    Choose one scenario. How did you identify the key activities to include in it?

There are several scenarios in the GreenDrive project which consists of several activities.  I am going to explore the drivers handling of the bus, which is one of the scenarios involved in the shopping trips. According to the case study the drivers are mostly volunteers and may drive the bus of a whole day or part of the day. A driver reports to work in the morning, picks a key from the office and signs for a bus and takes off driving to the day’s designated route picking the elderly on the way.   He then takes the elderly to the supermarkets where they conduct their shopping. After they have conducted their shopping the driver drive’s back through the same route dropping the elderly one by one at their designated alighting stations or points. In case of a problem along the way the driver calls to report what is going on to Doris who responds to emergencies.  At the end of his/her shift the driver returns the vehicle to projects premises, returns the key and sign to indicate s/he has returned back the vehicle. On Friday, the last drive refuels the fuel tank using money already allocated by Doris. In this scenario, the driver is the main actor and the activates involve are reporting to duty, picking the key and signing for the vehicle, driving the vehicle, picking the elderly at designated points, taking the elderly to the supermarkets, dropping them off at designated points, reporting any problem encountered on the journey, refueling the vehicle, retuning the vehicle and the key and singing for the return.

B2.3    How did you identify alternative uses to produce the secondary scenarios?

In use case modelling, alternative uses emerge as a product of failure in the main cases. The yare a created by alternative paths to the main parts use by the basic use case. For instance, in driver scenario above, if the sequence of activities is unable to take the usual designated course, the new course pursued is an alternative and the resultant use case an alternative case. An example, if a driver who has signed up for a vehicle is unable to return the vehicle leaves it to anther driver for an new shift, and the new driver return and signs for the return of the vehicle and the key, it is a diversion from the normal sequence of activities. Also only the driver who drives on Friday fuel the vehicle therefore, the sequence that involves refueling the bus is an alternative case.

B2.4    You will have needed to make some assumptions about the system. In real life what questions would you have asked to get the necessary information? Who would you have asked?

The questions I would have asked to several questions in order to come up with the necessary information for the creation the use cases modeling are and people I would have asked are;

Driver

The drivers undertake the bulk of the activ.............
