How Information Is Used
Organisations need to communicate with people inside the organisation as well as people
outside the organisation (suppliers, customers).
It is important to identify:
-
Who needs information
-
Who sends it
-
Who receives it
-
How it is processed
How ICT is used to support the above activities will help to tell you how an organisation
works.
It is common for an organisation to have a number of different ICT systems, each managing
different types of information.
Sometimes some of these systems will not link to other systems within the organisation.
This may simply be due to history or a defined development strategy.
Systems that do not interact well may lead to inefficiency within an organisation.
For example, if sales use a different customer database from accounts, this will require duplication of
work to maintain up to date records.
Also different versions of the same software can cause problems in the efficient flow of information.
Features of ICT Systems
Key features of ICT Systems include the following:
-
Types of data and how it is organised
-
Methods of data collection and data capture
-
Methods of data processing, e.g. batch, on-line, real-time transaction, multi- access
-
Data handling processes, e.g. sorting, merging, amending
-
Types of software, e.g. application packages, specially designed systems.
It is important that you understand the key features of each system and, more importantly,
the reasons for their use.
Typical ICT Systems
1 . Personnel and training systems
The personnel record system within an organisation is almost certainly linked to both the
payroll and training record systems (if they exist).
Typically, it holds for example details of each employee's:
-
name
-
staff number
-
address
-
telephone number
-
personal details
-
current position
-
employment history
-
education
-
skills
Most of this information will have been collected initially from the employee's job
application form and entered via a keyboard.
The Information stored IS confidential and subject to the Data Protection Act (1998) and, as such, must be
protected by appropriate security measures.
Depending on the size of the organisation, the information may be held in a simple
relational or
serial structure, or it may be
indexed.
The processing carried out may include sorting records in order, selecting employee records that match
specified criteria or searching for a specific employee.
Some of the information held within the personnel records may also be used as an input to
management information systems (MIS).
This is particularly true in service organisations that rely heavily on the skills of individual
employees.
Training records are a natural extension of personnel records.
Generally, only large organisations that have established staff development policies will maintain
training records and training plans for employees.
Such records will generally consist of simple tables and include details of training levels reached on
particular products or skills.
2. Accounts, finance and payroll systems
All organisations have some form of accounting or financial systems.
Such systems require speedy and accurate processing of multiple repetitive calculations in a standardised
way but, unlike payrolls, are generally achieved using
online processing.
Small organisations are most likely to use an
application package for accounting and financial systems but larger organisations are most likely
to have a tailor made system developed specifically for them through the processes of systems analysis and
software development.
Financial and accounting systems are designed to track and process the money that comes into
and goes out of an organisation.
As such, these systems form the cornerstone of the financial management of the organisation, and provide
the basis for any financial planning or budgeting systems.
Financial and accounting systems are generally linked internally to most other systems within
the organisation.
Particularly with such systems as order processing, stock control and management.
In larger organisations, these systems may also have external links to the Bankers Automated Clearing
System (BACS), and sometimes direct links with customers and/or suppliers,
Because much of the information contained within financial and accounting systems is not only
sensitive within the company, but could also be of value to other organisations, they will often be
protected by some form of security.
Most organisations have a computerised
payroll system, whether this is in-house or run by an external bureau. It is very often the first
system that an organisation computerises.
A payroll system needs speedy and accurate processing of multiple repetitive and relatively complex
calculations in a standardised way, generally using
batch processing.
Tax codes, rates of pay and hours worked are all linked to the employee's staff number.
This information can be the subject of regular changes and needs to be kept up to date to ensure the
accuracy of the payroll calculations.
The payroll information will usually be held in a simple relational or serial format.
Often there are links to communicate information externally to both the Inland Revenue and to BACS (to pay
employees' wages directly in to their bank accounts), and to communicate information internally to the
organisation's finance systems.
The system also produces pay slips automatically that may be mailed or given to the employee.
All payroll systems contain particularly confidential information to which rigorous security
should be applied.
Most payroll systems are based on application packages but even tailor made systems rely on
standard subroutines for tax and National Insurance calculations.
3. Research, design and development
Many of the systems used in the research and development (R&D) and design departments of
large organisations will have been developed to meet the specific needs of the organisation's products or
services.
However, many such departments also use other software:
Records will be kept on new products on trial, forecasts on how existing products will be
saleable, areas for future development etc.
4. Sales and purchase orders
Sales order processing (often called SOP, or just order processing) is responsible for the
management of orders and contracts placed by the customers of an organisation.
This is often implemented as a separate computer system, which generates an input link to sales when the
product or service has been delivered and an invoice has been raised.
It is likely that the order processing system has a direct link into the stock control and
production systems should they exist.
Many order processing systems will be integrated within an applications package with stock control.
The purchasing department within an organisation is responsible for raising purchase orders
for all goods and services from suppliers.
As such, it creates the input for the purchase ledger system.
These purchase orders are used to check invoices received from suppliers.
5. Stock control
Stock or inventory control systems are generally found in organisations that either hold
large numbers of items or small numbers of high value items, in store.
Each type of item is given a unique code either generated internally by the organisation, or as a code
provided by a supplier.
Other information held in stock control systems includes number in stock, location, re-order
levels, cost price, sales price and date received.
For high value items, there is usually a requirement to record individual item serial numbers.
Depending on the number of different items held in stock, the information is stored in either a relational
or an indexed format.
Stock control systems often have internal links to such systems as order processing and
production systems.
Sometimes they are linked to robotic picking systems within warehouses, but almost always have on-line or
paper based links.
Very often stock re-ordering is an automatic process.
Purchase orders are automatically generated and sent to suppliers by the purchasing department.
In larger organisations and where delivery time-scales are critical, direct external links are made with
suppliers.
If you telephone to order items from a mail order warehouse or catalogue the person you speak
to is almost certainly using some form of computerised SOP system linked to stock control that can tell
you immediately if the item is in stock.
This enables these organisations to ensure that customer orders are dealt with speedily and accurately.
Some form of security often protects these systems, because the information contained in them
is sensitive both internally and externally.
6. Internal e-mail systems
More and more organisations are using e-mail as the prime method for internal communication
with their employees.
It is very useful, not only to standardise procedures using selective mailing lists, but also to ensure
fast communication of information.
However, this is a system that requires careful management to ensure that only the right people receive
the right information.
Most email systems are based on applications packages.
7. Internet and Intranet
The
Internet and
Intranet, together with private LANs and WANs provide enormous opportunities for organisations to
achieve speedy and efficient communications both internally and externally.
The Internet has provided organisations with the ability to provide not only access for its
employees to external websites and information providers, but also the opportunity to promote its
activities relatively easily and cost effectively to a potentially enormous marketplace including the
facility for e- commerce.
An Intranet provides a further opportunity for organisations to communicate information
within an internal closed network to all their employees.
Organisations use many other ICT systems that depend on communications:
-
EPOS (electronic point of sale) information is communicated across networks by many retail
organisations.
This enables such organisations to keep up-to-date information on all stock levels, prices and special
discounts, etc. in all their head office and sales outlets.
-
Fax on demand provides an organisation with the ability to offer potential customers the
facility to telephone one of a number of dedicated telephone numbers, and by leaving their own fax
number, receive the information associated with the selected number automatically.
8. Product manufacturing systems
The term manufacturing systems is used to describe any of the wide variety of systems that
are provided to support organisations that actually make products. Any information system that automates
any part of the production cycle is classed as a manufacturing system.
Such systems vary from simple systems that carry out
bill of materials processing to systems that fully automate a complete production line.
Many manufacturing systems are based on packages but, in most cases, they are tailored considerably to
meet the needs of a particular organisation.
In many industries, without the aid of these information systems, it would be impossible to
manufacture certain products cost effectively.
JIT(Just in time) production systems are a very good example of a
manufacturing system.
They use sophisticated production scheduling techniques to enable a organisation to minimise stock
holdings while still meeting customer demand.
Glossary
Batch processing
Where the data to be input is collected to be processed together with little or no user interaction.
Bill of materials
Is a list of the parts needed to manufacture a single product.
Indexed
Each record has a unique index or key.
These are stored separately from the data.
This allows the records to be sorted more quickly.
On-line processing
The user interacts directly with the computer.
Relational structure
Data is stored in separate tables that are related to one another.
Serial structure
All data is stored in a single table in the order in which it was input.
