Unit 4 Outcome 2 IP&M - 2003

Formulate and justify strategies for developing, implementing and evaluating a networked information system in response to a social, economic or technological impetus for change.

This outcome will contribute 40 marks out of the 100 marks allocated to School-assessed Coursework for Unit 4. It will be assessed by one task.

Task

Description

· A written report

or

· A test

or

· A visual presentation (presentation file, poster).

Designing the assessment task

Teachers should design an assessment task that allows the student to:

· identify the reasons for changing an existing system, and propose and justify strategies for a new or modified networked information system, in response to the results of an analysis of the system and the proposed design. The analysis must incorporate the objectives of the new information system

· apply the development, implementation and evaluation stages of the systems development life cycle

· propose project management strategies to assist with the implementation of the proposed system

· have the opportunity to demonstrate the highest level of performance.

Resources and scheduling

Schools may determine the conditions for the task including access to resources and notes. Students should be advised of the timeline and conditions under which the task is to be conducted.

Performance descriptors

The following descriptors provide a guide to the standards expected when setting and marking assessment tasks. They describe the knowledge and skills typically demonstrated by students who have achieved scores within each range on the assessment task/s.

Outcome 2 Formulate and justify strategies for developing, implementing and evaluating a networked information system in response to a social, economic or technology impetus for change.
MARK RANGE	DESCRIPTOR: typical performance in each range
33–40 marks	All facts are accurately interpreted to correctly identify and classify the impetus for change. A clear system objective statement is provided. A complete set of criteria, which are logically connected to the system objectives, are proposed for selecting the equipment components and for evaluating the success of the information system. The criteria take into account all factors affecting the feasibility of alternative equipment components. All appropriate factors affecting the implementation of the proposed change are identified, as well as the key tasks associated with the implementation stage. All relevant aspects of coordinating the implementation of the system are identified in a project management plan, and appropriate techniques are used to accurately document these aspects. The proposed evaluation methods enable all relevant data to be acquired for each criterion. All methods are fully explained. A complete justification is provided, detailing how each strategy will enable the objectives of the new or modified information system to be met. The reasons provided are defensible and sound.
25–32 marks	Most facts are accurately interpreted to correctly identify and classify the impetus for change. A system objective statement is provided. The set of criteria for selecting the equipment components and for evaluating the success of the information system are closely connected to most of the system objectives. The criteria consider most of the factors affecting the feasibility of alternative equipment components. Most factors affecting the implementation of the proposed change are identified, as well as the key tasks associated with the implementation stage. Most aspects of coordinating the implementation of the system are identified in a project management plan, and generally appropriate techniques are used to document these aspects. The proposed evaluation methods enable most relevant data to be acquired for each criterion. Most methods are fully explained. A sound, but partially incomplete justification is provided of how the proposed strategies will enable the successful introduction of a new or modified networked information system. Most strategies are fully supported and are directly linked to the objectives of the new or modified system.

17–24 marks	Some facts have been overlooked when determining the nature and classification of the impetus for change. A brief system objective statement is provided. Some relevant criteria for selecting the equipment components and for evaluating the success of the information system are proposed; however, the connections to the system objectives are not always coherent. This criteria considers some of the factors affecting the feasibility of alternative equipment components. Some relevant factors affecting the implementation of the proposed change are identified, as well as some tasks associated with the implementation stage. A restricted list of aspects for coordinating the implementation of the system are identified in a project management plan. The documentation of the project plan contains some inaccuracies. The evaluation methods enable some relevant data to be acquired for each criterion. The explanation of some methods is adequate. An incomplete justification is provided of how the proposed strategies will enable the successful introduction of a new or modified networked information system. Some strategies are supported; however, some are not closely linked to the objectives of the new or modified system.
9–16 marks	Some facts are interpreted incorrectly resulting in an inaccurate statement of the nature or classification of the impetus for change. The system objective statement is not coherently linked to the results of the analysis and design. Limited criteria for selecting the equipment components and for evaluating the success of the information system are proposed. Some factors affecting the implementation of the proposed change are identified, and few key tasks are associated with the implementation stage are listed. The project plan identifies some relevant aspects for coordinating the implementation of the system. The techniques used to document these aspects are sometimes inappropriate or contains inaccuracies. The evaluation methods enable some data to be acquired for most of the criteria. The explanation of some methods is brief and reveals some misunderstandings of theory. The reasons described as to how the proposed strategies will enable the new or modified networked information system to be introduced lack coherence and detail.
1–8 marks	Errors exist in the interpretation of facts and attempts to identify the impetus of change and its classification reveal misunderstandings of theory. No system objective statement is provided. Little or no criteria for selecting the equipment components and for evaluating the success of the information system are proposed. A limited range of factors affecting the implementation of the proposed change are identified, and a few tasks are associated with the implementation stage are listed. Limited aspects of coordinating the implementation of the system are identified. The techniques used to document these aspects are generally inappropriate or contains inaccuracies. The limited evaluation methods will restrict the data gathering process. Superficial explanations are provided for the proposed methods. Few reasons are described as to how the proposed strategies will enable the new or modified networked information system to be introduced, and the descriptions reveals some inaccuracies or misunderstandings.
