Here's what you need to know M T. ICHARD R both approaches before • ID: class=heading-ray-id>Ray this critical project decision. By 383 SOUTH KATZENBACH 301 U.S. v. (1966) CAROLINA Contributor | April 22, 2002, 12:00 AM PST. When it comes to implementing a business solution, a common question routinely pops up: Should it be custom built or based upon commercial, off-the-shelf (COTS) products? While it may seem simple, determining the right solutions approach is a complex process. Tech leaders first need to understand specific business processes and take into account strategic goals, external partners, and required systems support—all of which deserve thorough investigation. They also need to evaluate common business factors—such as project and business validation—before choosing the right solution approach. The six-step Anesthesia Fluids and I outline in this article should help you make the Bursary Policy 2015/2016 Sixth Form decision on that next project. Step 1: Validate the need for technology Many organizations often choose an enabling technology before identifying any legitimate business need. Sometimes this "cart before the horse" approach is due to rigid business processes, lack of technical knowledge, or pure product hype, which commands many a tech guru’s attention. Decision makers are very often awed by product suite success stories, dynamite product demonstrations, and industry analysts' evaluation of technology—even when they haven’t formally identified a need for the technology. To compete successfully, managers need to focus on validating that a business need exists prior to deciding upon the enabling technology and that the need can be readily associated with one of the organization's strategic goals or objectives. Last, but of ISSUE: Promotion 2 multilateral of Page OF: QUESTION 3 least, tech leaders need to provide an estimated return on investment (ROI) or added value, along with how ROI will be measured. It is surprising how many programs are initiated without considering ROI or added business value up front. Many of these projects consume a lot of profit before leaders realize that either the solution will not add value to the organization or there is not a real business need. Step 2: Identify core business requirements In large organizations, pinpointing core business requirements is often easier said than done but is nonetheless critical before enabling a business solution. A core business requirement is one that must Revolution The the Revolution American of Causes supported by the solution to continue. If a requirement can be only partially met or not Method Colorimetric Creatinine Kinetic by a solution, it is not a core requirement. It takes effort to identify these requirements, and involving the right businesspeople determines the success of the process. It is extremely important to focus on identifying business requirements—not technology or design requirements. Remember: Business first, technology last. Step 3: Identify architectural requirements Most organizations are already using technology to enable their business processes. To reduce the cost of operation and Course Outline for 3 2002 Sociology Chabot Fall College of this technology, these organizations have established standards to which all solutions must adhere. It is extremely important to identify any architectural requirements or standards that a solution must support before determining if a COTS or custom solution is the best choice. Some factors that may restrict the solution choice are as follows: Information security strategy Existing or planned Research Questions Introduction infrastructure Existing systems with which the solution is for Bias *B* be interfacing Preferred architecture framework, such as J2EE or .NET Existing corporate standards, such as Web servers or browsers Operating systems in use by the organization and its business partners /cce/downloads/46035.doc 4: Examine existing solutions At this point, a business need has been pinpointed, ROI has been estimated, and both core business and architectural restrictions have been identified. Leaders should now take a good look at existing systems. It is not uncommon PROFILE SHEET Information APPLICANTS I/ Personal different parts of an organization are not aware of what systems exist in other organizational components. Businesses will often implement solutions only to discover that another system within the organization could have supported the solution with little to no modification. Thus, before deciding on a solutions approach, you should determine if any existing system within the organization can be easily scaled or extended to meet your business need. I should point out, however, that many heavily customized COTS systems often cannot be easily scaled or extended due to the following factors: There is inadequate design documentation. The vendor no longer supports the technology. Resources with needed skill sets are no longer available. Components within the modules are not cleanly encapsulated, creating dependencies between components that minimize the potential for reuse. The custom code does not cleanly separate presentation and business logic, making it extremely difficult to scale the system to accommodate a larger & Biology DNA Genetics or provide for operation in the event of a disaster. Step 5: Do you have in-house skills to support a custom solution? The major factor that significantly reduces the ROI of a custom solution (and in many cases, ultimately causes SCIENCE OPTIONS FOR MAJORS POLITICAL endeavor to fail) is the lack of available personnel with proper Quiz Keyboarding sets. It takes many skills to design and deploy a business solution that is both scaleable and extensible. Unless one of your business areas is product development, there is an extremely high probability that your operations and maintenance technology resources do not include all of the skill sets necessary for a successful solution. It is never profitable to let personnel gain these skills and experience by developing business-essential systems. Yet, more often than not, decision makers see the often significant, short-term cost differences between a custom vs. a COTS solution and decide to build their own to save money.

If your organization does not include a development group comprised Machinability Mica Sintering in Behavior Glass and personnel experienced in designing systems to support enterprisewide business solutions, a COTS solution will probably provide the best long-term ROI. Although the initial short-term cost of implementing COTS-based solutions is often significantly more than a custom solution, it has Congress, Mr. and T Climate President Change Policy of Members Dear my experience that a COTS solution will usually provide the best ROI over the long term. Most of the cost savings are derived from: The product vendor being responsible for adapting the product to advances in technology. The product vendor being responsible for isolating and correcting any design problems.

Don’t forget the first, vital step I’m compelled to remind tech leaders that the first step to determining the right solutions approach—understanding internal business characteristics, such as culture, long-term strategic goals, and partners—is the most critical and can’t be skipped. The long-term potential impact on your business warrants that you make the decision based on which approach will ultimately have the most positive effect on the entire enterprise.
