Introduction to ERP

ERP stands for Enterprise Resource Planning . ERP systems are the kind of software tools which are used to
manage the data of an enterprise. ERP system helps different organizations to deal with different departments of
an enterprise. Different departments like receiving, inventory management, customer order management,
production planning, shipping, accounting, human resource management, and other business functions. Basically,
it is the practice of consolidating an enterprise’s planning, its manufacturing, its sales and marketing efforts into
one management system. It combines all databases across different departments into a single database which can
be easily accessible to all employees of that enterprise. It helps in automation of the tasks involved in performing
a business process.

levels of competition. To face such competitions, successful corporations should follow the best business practices in the industry.

better management of the entire supply chain. All these need faster access to accurate information, both inside the organization
and the entire supply chain outside. The organizational units such as finance, marketing, production, human resource development
etc. need to operate with a very high level of integration without losing flexibility. ERP system with an organization-wide view of
business processes, business need of information and flexibility meet these demands perfectly. One of the developments in
computing and communication channels is providing right integration among them.

Evolution of ERP System

Enterprise Resource Planning (ERP) is made to automate any task. With ERP, it is easy to manage every
department under one single database. This consumes not much time and is easy and fast way to do work with.

used approach for production planning and scheduling in industry. It is the approach embedded in many
commercially available software applications.

,The function of MRP is to provide material availability i.e, it is used to produce requirement quantities on time. This
process involves monitoring of stocks and demand, leading to automatic creation of procurement proposals for
purchasing or production. The main objective of MRP is to determine which material is required, quantity required
and by when it is required.

2. Manufacturing Resource Planning (MRP II) –
Developed in 1980s, Manufacturing Resource Planning is an expansion of closed loop MRP for managing an entire
manufacturing company. This system provides an information that is useful to all functional areas and encourages
cross-functional interactions.
It supports sales and marketing by providing and orders promising capability. It is a broad-based resource co-
ordination system involving other areas of a firm in planning processes, such as marketing, finance and HR.

create a problem that they did not receive information quickly, which is essential for making a
competitive advantage.

open orders. Whenever there is need to look for past status to find trends and patterns it become
difficult. That aid better decision-making.
3. No doubt that data is integrated within the system, but there is no integration of data with other
enterprise or division systems and it does not include external intelligence.

requires significant investment in hardware, software, and personnel, as well as training and
consulting costs.

be complex and require specialized knowledge. This can lead to delays and additional costs.

practices.
