Bespoke software is made specifically for an organisations purpose. It's usually for a single end-user. You cant get this off the shelf and it is tailor made to meet the requirements and functionality of the organisation.
From the pre-release, it shows that Endurance want to use a Bespoke solution

"Hope" want to have a pre-packaged/off-the-shelf software which is available to buy any time. It is usually generic software, e.g. spreadsheets which are used for accounts. It's not specific to the organisation and is available for everyone to buy.

Hope that helped.

If a question comes up on this, are there any key advantages and disadvantages to mention?

Um from the top of my head

Advantages for bespoke:
More specific to organisation (particular functions can be requested by the client for the system to include, this cant be done with off-the-shelf as that is generic)
Integrate it with other systems
Easier to use as it is made specifically for the organisation
Improve efficiency/work of organisation

Disadvantage:
High cost
Time-consuming; takes a lot of time producing the system (Systems development life cycle)
The staff may need training to use it


Advantages of generic:
Training may not be needed as these are generic softwares.
Cheap
Can be purchased any time, so no time-constraints

Disadvantages:
Not specific for the organisation
May not include all the functionality needed by the organisation

Different types of testing during the SDLC:

Functional testing - checks the system being developed meets both the system and business requirements It involves checking the validity of formulas and calculations as well as testing that the user interface works as it should.

System Testing - Once software used by the system has been tested, the whole system can be tested. It is tested by using certain hardware, users and environment which match the system being used in the real-life situation

Operational Testing - Testing performed by the end-user on software which is being used in its normal operating environment.

User Testing - Allows teams of users to test the software for ease of use, consistency of design, links that do not work, use of language, graphics ,etc Usually this is done by giving the users a questionnaire.

Anyone have condensed note on INFO3? There's no way I'm getting through it in 2nights -_-

Techniques for testing

Test harnesses; are used in software testing for automating the testing process. Test harnesses consist of software and test data which will run the developed programming code under different conditions and monitor its output against the output that should have been produced. The main advantage in using test harnesses is that they automate some of the testing and this means its quicker and the quality of the final software is better.

Prototyping; this involves producing working versions of the ICT system at different stages during its development. The user is given each version to test and evaluate and any problems can be ironed out before the next improved version is produced.
It's a quick way to get feedback from users, you involve the users right from the start so you end up with a product that matches the user requirements and expectations. This is a much better way than to leave it to the end.

Scalability testing; is a type of performance testing focused on ensuring the application under test is able to cope in an increased workload.

Multi-platform testing; is aimed at demonstrating software can be ported to specified hardware or software platforms. (ensures it can be transferred to other software and be compatible with the hardware/software)

Volume testing; confirms that any values that may become large over time (such as accumulated counts, logs and data files) can be held by the program and it will not cause it to crash or slow down.

Simulated environments; sometimes it is difficult to see how a large system will behave when used with hundreds of terminals until you use that many terminals. Therefore the use of simulated environments gets around this problem by behaving as though it is being used by large number of terminals, this allows the developer to test the system before it goes live.

Iterative vs Linear Methodologies?

Advantages and disadvantages?

[Indyy]

What would you mention in a question about Inhouse vs Outsourcing?

Advantages and Disadvantages?

[aneesa10]

Hey guys! Does anyone know which topics have a high chance of coming up? I have a feeling topics 2, 5, 10, 11 and 12 might?

Here are some Qs i think will have a good chance of coming up!
...What is meant by outsourcing?
....What is a mission statement?
.....What measures can be taken to ensure data is secure?
....What makes an effective ICT Solution
....WHat is JAD? & how can it benefit team HOPE?
What is a package system?
What is a Bespoke system?
What are the advantages/ disadvantages of ICT being outsourced?

What does mission statement mean? and what does JAD stand for?

[thairshan]

List of questions that I think may turn up:

1. How can you ensure the data is stored safely and securely?

2. Compare the approach of team 'Hope' vs team 'Endurance' in establishing requirements

3. Compare how the teams propose ICT to be used for publicity

4. Benefits/drawbacks of outsourcing vs inhouse

5. Identify the most appropriate form of ICT provision

6. Appropriate choice of ICT software to meet the requirements - customer records, publicity, accounting, etc.

[thairshan]

here are some more


What aspects do the team ned to look at when developing the ict policy?

What stages of development will you follow to develop the solution ?


Why do you think this team will win?

Why do you think the team will loose?


identify operational, strategic, tactical needs for each type of hope and enduaracne?

Data storage - security, backup, recovery

· System Life Cycle- particularly approach to the Analysis, identifying requirements, talking to relevant individuals (business team vs university staff)

· Bespoke vs off-the-shelf systems

· Linear vs iteractive methodology

· Creating ICT strategy - especially thinking about finances, alignment to business goals

· Recruitment - how many staff, what sort of skills

· Use of ICT in publicity at youths - mailshots vs social networking

· Outsourcing vs inhouse

Hey mate do u have any practice papers for info 3?

[01nathan]

There is a really good practice paper done by zigzag for June 2012 based on the pre release with the mark scheme it is a fantastic resource however i only have the first paper, does anyone have the second. This would be so beneficial for all of us !

What does mission statement mean? and what does JAD stand for?

Mission statement - what is the purpose of the organisation (non-profit charity organisation, public school etc. etc.)

JAD - Joint application development, its the analysing stage within developing a system, its where a group of people sit down and discuss what they want from the system. With this you will get a more broader client requirements (if there are people at all stages - tactical, strategic and operational - taking part) opposed to interviewing someone who is at the strategic level of an organisation, he will not know what someone at the operational level of the organisation would want from the system. (Works very well for enterprise systems)
