Functions of Enterprise
Enterprise
Business processes & Information Systems
Def: Manner in which work is organized, coordinated, and focused to produce a valuable product or service.
-- Cross-Functional Business Processes transcend boundary between sales, marketing, manufacturing, and research and development (e.g., order fulfillment process…)
Ways in which management chooses to coordinate work
Systems from a Functional Perspective
Examples of Business ProcessesFunctional Area Business ProcessManufacturing and production
Assembling the productChecking for qualityProducing bills of materials
Sales and marketing Identifying customers Making customers aware of the productSelling the product
Finance and accounting Paying creditorsCreating financial statementsManaging cash accounts
Human resources Hiring employeesEvaluating employees’ job performanceEnrolling employees in benefits plans
• Focus on ‘Functions’ rather than ‘Processes’• Applications developed over time. • Inconsistent, redundant Data• Time lag in information delivery
Managerial Control Difficult Process Productivity Monitoring Difficult
• Reaction to change slow
