Re: Aqa info 3 - 12/06/2012business goals are the aims that has to be achieved.(Original post by xMaGic)
Define Business Goals and ICT Strategy?
strategy is a long term plan to be able to achieve a goal. -
Re: Aqa info 3 - 12/06/2012what i did in past papers is a mind map with 20 points including keywords about what the question is asking, then i numbered each point to structure how i will be writing. as i answered the question everytime i expanded about the point mentioned in the mind map i related back to the question.(Original post by mohit93)
Anyone able to tell me how to answer and structure the 20 mark essay?
hope this helps

The three levels in an organisation;
Strategic
Tactical
Operational
The strategic level consists of directors, chief executives, headteachers, etc. Basically every one on the top.
The tactical level contains managers, department heads supervisors
The operational level contains accounts clerks, teachers, sales staff ,etc
The need for information is different for each level. Strategic people need high level overviews with little detail.
Tactical people need summaries and reports to decide how to manage a problem
Operational; involved with information about day-to-day tasks, e.g. transactions
Strategic tasks;
- Takeovers of other businesses
- Decisions regarding expansions
- Decisions about the introduction of new products/services
- Decisions about major expenditure on new ICT systems
Tactical tasks;
- Completed by managers to achieve the objectives that are set by chief executives. They make decisions using operational information. For example, if a certain product they produce is not selling well, they can decide what to do.
Operational: routine day-to-day tasks which keep the business or organisation functioning. The majority of operational tasks deal with all the transactions which take place when running an organisation
- Paying wages
- Ordering stock
- Paying for stockLast edited by xMaGic; 11-06-2012 at 16:35. -

Define Business Goals and ICT Strategy?
Advantages;
- target is set to aim for and so the actions within the organization can be focused
- can be used as a motivational tool by offering rewards at the end of a successfully completed project.
SMART aims
SPECIFIC - easily identified and understood
MEASURABLE - goals are broken down into milestones, measured to ensure that overall performance is on schedule
ACHIEVABLE - pointless and demotivating if it can not be achieved
RELEVANT- must be relevant or performance may be misunderstood and most likely to fail targets
TIMESCALE - needs a clear time frame including start and end time. this helps to predict success of task
Also main factors that also influence an ICT strategy within an organisation;
- Available finance
- Legacy systems
- geography of clients - location, characteristics (costs, communication etc)
- business fulfillment (motivation, personnel skills, relationship between staff)
- external factors (legislations)

Types of ICT System and their use:
CRM: This system help manage day-to-day relations with customers.
- They improve the effectiveness of communication between the organisation and its customers
- They allow organisations to better understand each customers value to the organisation
- They allow the analysis of past orders that the customer has made, which allows the organisation to give advice on them what to buy next (targeted advertisement/narrow casting)
- All communication with the customer is recorded so there is coordination between the web, e-mail and telephone. -

Transaction processing; processing of each transaction as it arises. E.g. a customer paying for goods
Workflow; the scheduling of independent tasks using manual or automatic system
Management information system (MIS); an organised collection of people, procedures, resources, designed to support the decisions of managers. -
Re: Aqa info 3 - 12/06/2012Linear vs interactive what??
If you mean system development and you're talking about linear vs rapid application development (RAD)
Then linear is make a plan, complete the plan which takes a long time as it is from scratch completely bespoke opposed to RAD which is a little more automated, the code is provided by generators, GUI builders, CASE tools, DBMS. A little more generic outcome I guess, also RAD uses prototyping as it is an iterative development methodology.

Re: Aqa info 3 - 12/06/2012Yes, system development methodologies.(Original post by Joanna42)
Are you talking about methodology? -
Re: Aqa info 3 - 12/06/2012Linear and interactive are the development methodologies.
Linear methodology has waterfall method to develop the systems.
Waterfall is basically when the project is divided into sequential phase.Tight control is maintained over the life of the project through the use of extensive written documentation, as well as through formal reviews and approval by the user and information technology management occurring at the end of most phases before beginning to next phase.
Iterative methods include prototype technique. This means going through a process several times and coverage on a suitable solution ans so basic principles of an iterative methodology is that the phases are not standalone but an approach to handling selected parts of a traditional methodology.
Strength of waterfall:
Ideal for supporting less experienced project teams and project managers.
DEsign reviews helps to ensure the qua;oty, reliability and maintability of the developed software.
Progress of the system is easliy measurable.
Weaknesses of waterfall:
Inflexible, slow costly and cumbersome due to significant structe and tight controls.
System performance cannot be tested until the system is fully coded
Produces excessive documentation and keeping it updated as the project progresses is time consuming.
Most suitable for the development of mainframe based systems, where there are clear objectives and no pressure for an immediate implementation.
Iterative prototyping strengths
It deals with inability of users to accurately specify their information system needs and the environment they will operate in.
Can be used to improve communication between system developers and other project stakeholders.
Quicker compared to waterfall methodology.
Weaknesses:
Insufficient documentation may result ion too little records being kept for future maintenance and support.
Hope that helps

Here is the first paper, does anyone have the second?
Second paper, no mark scheme
Errr... Anybody have the mark scheme for the second zigzag paper?Last edited by Chemzoik; 11-06-2012 at 21:16.
