1. Introduction

1.1. Client Identification

My client is Imogen Summer-Rooney, but she likes to be called Luki. She has some knowledge about computers. Luki's main uses for a computer are email, internet and word processing. At the moment Luki uses an Acer Aspire 7535 laptop to which is running a 32 bit version of Windows 7.

She is a self-employed designer, specialising in re-working vintage clothes to something that can be worn by the youth’s image of today.  Luki currently offers these designs off her Facebook, Tumblr, twitter and website page. Luki runs a team consisting of a photographer, two male models and two female models who all are her closest friends. She’s named this group ‘The House of Sharps’ and has plans to expand in the near future.  Luki works alone doing the designing, printing and general creation of her products but she sells the clothes through her friends.

Luki would like a new system, as her current system is unorganised and is recorded simply through writing. Her business is not very big so she would like a system for when she expands she can stay organised. With the current system there is a difficulty in trying to record all data when there is a bigger order. Luki would like to be able to have an ordering system along with a database system to which data can be stored in a secured manner.

1.2. Define the current system

The current system to manage all the data is a manual system of which involves writing the buyer and design data on multiple forms, and storing the forms in folders which contain all the other data - this includes the price of the products. The data that is collected from the buyer and the design is output to a form, of which is stored in her folder system.

Currently, for one buyer that buys some clothing, Luki writes down who, when, how much, etc of the product shes sold and to whom.

Despite this being an unfinished draft version of a piece of coursework it is showing promise. The structure of the document is comprehensive and it is clearly laid out. The student has a clear grasp of the problem and has done some research into the issues with the current system. It would be beneficial to use one other piece of analysis technique, for example, observation to give more depth to the situation. It is a problem which definitely exists and therefore it presents a very good project subject. One key thing that needs to be looked at again is the objectives (in their many forms). These are so often overlooked by students for what they really are - fundamental to the success of an A level project. If done properly they provide a real scaffold for the student to complete their work around and keep referring to them. For example, when the user eventually produces some hand drawn designs or prototypes interfaces for the system they can annotate what they have done and refer to the objectives as justification for design layout or inclusion of certain functionality. If you took the parts of this work that are complete it is a strong three stars.
