A02 Implementation Commentary

A02 – Implementation Commentary

I split the design problem into a number of different sections, which are explained:

Analysis of Problem

The Analysis of Problem is when the problem is recognised.

Design of Solution

The Design of Solution is when everything from the Analysis is taken into account, and an appropriate solution is drawn up.

Implementation

The Implementation is when the Design is transferred into a real thing e.g. the touch screen presentation.

Testing

This is where the solution is examined to find any faults or spelling/grammar errors. At this stage, any changes are made to the system.

Evaluation

This is where the final system is evaluated, and any things hat would be done differently next time are mentioned but not carried out.

There are various different inputs, processes and outputs which I had to control to make my presentation. These are very important to be able to make the foundations to the main presentation:

Inputs

All the data that was input was:

The NHS logo which I copied from a website.
The map which I copied from MultiMap, which is on the final slide.
The names and positions of all the staff who work there
All the information about the health centre i.e. the policies

Processing

I had to paste the NHS logo into PhotoFiltre and then crop it, and then re-paste it into the presentation.
Similar to the NHS logo, I had to paste the picture into PhotoFiltre, crop it and then re-paste it into the presentation.
I had to cut the table which I produced in Microsoft Excel, make it the correct size and then place that into the presentation, moving it to the correct position.
I had to change the font and size of the policies writing and then make the background white of the textbox, and move it into ...

Accuracy and Spelling / Testing

Accuracy and spelling/grammar is very important when doing a professional presentation like this. When data is inputted, it’s creditability needs to be monitored just to make sure that it is always telling the truth and the right thing. Also, if spelling is incorrect, it looks very unprofessional and irresponsible. When data such as Opening Times are inputted, it is essential that they are correct and always up-to-date as customers need to know the vital information. Errors could be made when the data is being typed into the system, or when the original data is being printed/produced. After data has been inputted and checks have been made to ensure it is correct, the presentation needs to be stored safely so that changes are not made accidentally. The system needs to be stored on a password-locked server which can only be accessed by the vital few people who run it. This means that someone inexperienced cannot have access to the system and change it. Proof-reading the document to see if there were any visible mistakes, and the Spelling and Grammar checker on Microsoft checked any spelling mistakes.

Storage Devices

A storage device is used to save all work done by a user and to ensure that no information is lost. There are two main types of storage devices:

Read Only (ROM) – is not ever erased from the memory when the power supply is switched off i.e. turning the computer off will mean the document will still be there when it is turned back on again, all the information is permanent. This is sometimes called ‘non-volatile memory’.
Random Access Memory (RAM) – this is erased when the power supply is switched off i.e. turning the computer off will mean the document will not be there when it is turned back on again. This is sometimes called ‘volatile’ memory.

The main storage devices I would use for my hard disk would be:

Hard Disk – This is built into the computer, and things can be saved to it very easily. They are normally quite large in capacity, so many, many text documents can be stored at one time. This works by a magnetic head reading the information off the hard disk as it spins around very quickly
Floppy Disk – Floppy Disks are portable storage devices that can hold around 300 pages of text. But actually they only hold 1.44MB of stuff, so often pictures or word art will not fit onto the floppy.
USB Drive – This is a reasonable new method of portable storage, and they normally have a much larger free space than a floppy disk.

I created a presentation on Microsoft PowerPoint. I did this by adding a background picture into all the slides. Then I went on to put the rectangular buttons on the right hand side of the slide. The buttons on this list were then hyperlinked to the correct slides, so when that button was pressed, the computer would be directed to that wanted page. I then inserted a text box and wrote in the information; I decided to make the background of the text white to ensure it could be read easily. Headings were then inserted, as were the relevant pictures.

My presentation went well, but some changes had to be made on the way. When I first produced it, there was barely any colour on it, and it was not very attractive to look at. Inserting a background picture into the presentation, which made it look a lot better to look at, rectified this. There was various spelling and grammar mistakes on the presentation, and using the Spell Checker helped this. There was no colour on the heading of the Opening Times table, which meant that users might get confused. I changed this by making the heading of the table yellow. Sometimes incorrect words were used: I described the staff as ‘okay’ but then changed that to ‘good’ which improves the reputation of the Health Centre. Some of the important writing did not stand out enough, so I changed the text colour to purple to help this.
