Transcript of Unit 11 - Systems Analysis and Design

Unit 11 - Systems Analysis and Design Achieving
Like other units to pass this Unit you need to meet all 6 Pass criteria to pass the unit.

To pass the Unit with a merit you have to meet all 6 Pass criteria and all 3 Merit Criteria.

To pass the unit with a Distinction you have to meet all the 6 Pass criteria, all 3 Merit criteria and the 2 Distinction criteria. Provisional Assignment names, dates and criteria:

Assignment 1 - Principles of Systems Analysis and Design
Hand out date: November 2012
Hand in date: November 2012

P1, P2, P3 & M1


Assignment 2 - Project Solution
Hand out date: December 2012
Hand in date: January 2013

P4, P5, P6 & M2, M3 & D1, D2 You will be expected to:

Work on your own Workbooks;
Studying video demonstrations;
Apply principles to real world problems and systems;
Learn theories, principles, methodologies, models, work in groups;
Create and give presentations;
Create diagrams;
Use and develop problem solving skills to provide solutions. Pass Criteria - elements and range P1 - Outline the principles of systems analysis.

Principles:
development life cycle models;
developmental tools and techniques;
Key drivers: business need, e.g. need for growth, company acquisition, need to
increase productivity, legal requirements. P2 - Illustrate the stages of a development life cycle.

Development life cycle models:
Waterfall;
other e.g. Spiral, Rapid Applications Development (RAD);
stages e.g. initiation and feasibility, investigation, requirements analysis
and specification, design (logical and physical), build systems, testing,
implementation, maintenance. P3 - Explain the benefits of structured analysis.

Structured analysis:
benefits e.g. reduced risk of projects running over-budget or over-time, good
quality software that meets requirements, manageable projects, maintainable
systems and code, resilient systems. P4 - Carry out a structured analysis of a specified business process.

Investigation:
techniques e.g. interview, questionnaire, meeting, observation, document
analysis, data analysis;
sensitivity in collecting information and observing individuals at work. P5 - Produce a requirements specification for a business process.

Requirements specification:
contents e.g. scope, inputs, outputs, processes, costs and benefits,
recommendations, alternative solutions. P6 - Produce a design for a specified system requirement.

Design:
inputs and outputs e.g. screens and report design;
data e.g. data flow diagrams, data dictionaries, entity relationship diagrams;
process descriptors e.g. decision tables, flow charts, structured English. Merit Criteria - Elements and Range M1 - Discuss the most appropriate uses of different development life-cycle
models.

Development life cycle models:
Waterfall;
other e.g. Spiral, Rapid Applications Development (RAD);
benefits. M2 - Suggest alternative solutions.

Alternative solutions should be suggested with valid reasons for their inclusion. M3 - Explain any constraints on the system design.

Constraints:
on the design e.g. costs, organisational policies, timescale, legacy systems, available hardware platforms. Distinction Criteria - Elements and Range D1 - Analyse costs and benefits.

Analysis: as related to the chosen methodology;
cost benefit analysis.
D2 - Generate comprehensive design documentation independently.

Design:
inputs and outputs e.g. screens and report design;
data e.g. data flow diagrams, data dictionaries, entity relationship diagrams;
process descriptors e.g. decision tables, flow charts, structured English. Pass Criteria
1 - Outline the principles of systems analysis.
2 - Illustrate the stages of a development life cycle.
3 - Explain the benefits of structured analysis.
4 - Carry out a structured analysis of a specified business process.
5 - Produce a requirements specification for a business process.
6 - Produce a design for a specified system requirement. Merit Criteria
1 - Discuss the most appropriate uses of different development life-cycle models.
2 - Suggest alternative solutions.
3 - Explain any constraints on the system design. Distinction Criteria

1 - Analyse costs and benefits.
2 - Generate comprehensive design documentation independently. Suggested Textbooks

Yeates D and Wakefield T – Systems Analysis and Design, 2nd Edition (FT Prentice Hall, 2003) ISBN-10 0273655361, ISBN-13 978-0273655367 Aim and purpose

The aim of this unit is to enable learners (you) to gain an understanding of the principles of systems analysis and equip you with the skills to analyse business requirements and design solutions to meet business needs. Learning outcomes
On completion of this unit a learner should:

Understand the principles of systems analysis and design
Be able to carry out a structured analysis of business systems requirements
Be able to design business systems solutions. Activity 1

Research the current Systems Analysis jobs market in the UK:

Using a suitable search engine (Google UK is very good for this) – enter the following into the search engine:

+“Systems Analyst” +job

Look for a range of jobs in this field – from Junior Analyst to Senior positions. You should come up with at least 5 different jobs
Once you have found jobs in this field:

Write down the title of the job and what company the job is with.
Write down the salary range (must be UK £).
Note any additions to the salary – e.g. bonus schemes or provision of a car.
Also note the area of the country/world.
Break down the explanation of the job into the following areas and list what you find:

What at the general skills required – e.g. ‘10 years experience as an analyst’, ‘finance background’, ‘programming experience’…
Are their specific skills – e.g. ‘C++ programmer’, ‘Excel’, ‘Business Objects experience’…
Finally, list the personal skills – e.g. ‘good communicator’, ‘excellent negotiation skills’, ‘strong team work skills’…
