Internal functions can have many definitions this I because there are many factors which relate to this topic. A company functions internally when it makes certain of its developments e. g. using its finance system for many different reasons such as:
* Sales Operations
* Human resources
* Marketing purposes
* Purchasing or Designing
Without using external financial resources the organization may be unable to ensure Health & Safety at work and be able to pay VAT, tax and National Insurance.
This meaning that a company will be breaking the law. Internal financing and external financing are both extremely important to the business, Even if internal financing is favoured by the company, internal financing can become harmful when it is used abusively. Its cost being zero, internal financing can encourage not very cost-effective investment projects. Internal functions include:
* taking customer requests in account
* dealing with customer complaints
* working out the profitability of each product
* producing sales targets for a product
* dealing with expenses of sales staff
* setting sales targets for individual members of staff External functions include:
* Supplies from external companies
* Government funding e. g. grants Analysis And Design Methodologies Analysis and design methodology is used for many different circumstances for instance developing high-quality systems and databases.
software development methodology involves certain aspects which include:
* Firstly analysis, which deals with the design requirements and overall architecture of a system, and this concentrates on describing what the system does overall whilst describing key aspects of the software
* Secondly, design which translates system design layouts into programming language
* And last, programming which inputs these programming attributes into the system.
The idea behind an object-oriented language is object breaking down the software system, once in the separate objects it combines the data and the functions that operate on this data into a single unit, the object. Objects are then discussed and built in turn by modelling its real-world attributes.
Object-oriented analysis and design methodology cuts down development time and costs, this leads to a faster time to market this giving a massive advantage to the user it also leaves time for producing more flexible, easier maintainable object-oriented systems As it is done in segments whilst being made this system does not include a fixed ending though it saves time to complete the system it also per-longs time as it has to keep being proof read to make sure its correct.
