ERP software provides integrated management of key business functions like finance, supply chain, customer management. It offers advanced reporting of trends and patterns to help decision making. Rightsizing is the process of restructuring a business through cost cutting or workforce reduction to optimize profits. When deciding rightsizing, companies consider financial losses, reduced sales, statutory compliance and individual employee criteria. Effective rightsizing involves in-house or outplacement of employees, clear communication and an unbiased selection process. ERP implementation should be considered for large organizations or those with incompatible legacy systems based on activity scope and cost-benefit analysis.
