CIS335: Business Systems Applications

A complete guide to SNHU's CIS-335 Business Systems Applications, covering the variety of business information systems — CRM, ERP, helpdesk management, payroll, supply chain management — and how to identify, propose, and justify the right system for a given business need.

UndergraduateSNHUBusiness Systems ApplicationsAPA 7th Edition

CIS-335 covers a variety of business types and the appropriate information systems to help run them. Students demonstrate an ability to identify and model a business process with the goal of improving it with a business system application — examples include CRM, ERP, helpdesk management, payroll, accounting, decision-making, and supply chain management systems. The course also covers the pros and cons of acquiring information systems via cloud services, purchasing software, public domain software, or building in-house, with hands-on experience proposing, justifying, and quantifying the effectiveness of information systems implementations.

Matching the right system to the right business process

The course covers a genuinely wide range of business system types — CRM, ERP, payroll, supply chain — because different business processes require genuinely different specialized systems, and matching the right one to a given need is itself a core skill.

Build versus buy: evaluating acquisition options

CIS-335 covers the real trade-offs between acquiring information systems through cloud services, purchasing software, public domain options, or building in-house, since this acquisition decision carries significant cost and risk implications beyond the system's technical features alone.

Worked example: build versus buy trade-off

  • Building in-house: Fully customized to the business's exact needs, but costly and slow to develop
  • Purchasing/cloud service: Faster and cheaper to implement, but may require the business to adapt its processes to the system rather than the reverse
  • Lesson: CIS-335 teaches that this acquisition decision requires weighing genuine trade-offs, not just picking whichever option seems technically superior

Frequently asked questions

Why does CIS-335 cover such a wide range of business system types (CRM, ERP, payroll, supply chain) rather than focusing deeply on just one?

Different business processes have genuinely different information system needs — customer relationship management, resource planning, payroll processing, and supply chain coordination each require specialized functionality that a single generic system can't adequately provide — and a business systems professional needs to recognize which type of system actually fits a given business problem. CIS-335 covers this breadth because matching the right system category to the right business need is itself a core, transferable skill regardless of which specific system a student later specializes in.

Why does CIS-335 require students to quantify the effectiveness of information systems implementations rather than just proposing systems?

A system recommendation that sounds reasonable in theory still needs to demonstrate genuine, measurable business value once implemented, and without a way to quantify effectiveness (cost savings, efficiency gains, error reduction), a business can't actually verify whether the system investment paid off. CIS-335 requires this quantification skill because real business systems work involves justifying decisions with evidence, not just proposing solutions and assuming they'll work as intended.
