QUESTION $5$

The value chain is a business model used to examine all company activities involved in taking a product or

service from idea to sellable item. Ideally, companies can use the value chain model to strengthen their point of

view and widen their profit margin leading to more efficiency and fewer costs. Discuss the Primary and Support

activities of the Business Value Chain model. Choosing the Right DSS System for Your Needs

The most appropriate DSS depends upon organizational maturity, complexity and, to a certain extent, size. In small

organizations, hybrid systems may suffice. If the organization is new to analytics, historical DSS systems would be a good

place to start, while those involved in activities such as trading and commodities may benefit more from a predictive decision

support system example.

Without a doubt, the greatest benefit lies with selecting a prescriptive analytics derived decision management system that

models the business and provides the ability to determine the most advantageous decision based on certain criteria, such as

revenue and profitability. While entailing a greater investment in resources and money, such a solution has a greater probability

of exceeding expectations and achieving a greater ROI. Additionally, it takes the guesswork out of decision

$-$

making, and

because the model replicates the business, this type of decision support system example is more likely to offer feasible and

rational solutions.

Day Decision Support System Examples

Decision support systems operate at many levels, and there are many examples in common day

day use. For example, GPS

route planning determines the fastest and best route between two points by analysing and comparing multiple possible options.

Many GPS systems also include traffic avoidance capabilities that monitor traffic conditions in real time, allowing motorists to

avoid congestion. Farmers use crop

planning tools to determine the best time to plant, fertilize and reap. Medical diagnosis

software that allows medical personnel to diagnose illnesses is another example. Most systems share a common attribute in

that decisions are repetitive and based on known data. However, they aren

decisions, something many early GPS users discovered.
