TPS is short for Transaction Processing Systems and is the simple business system that carries out the operational level (analysts) in an organization. A TPS will usually provide the base for other information systems within the organisation. Business activities such as sales, receipts, cash deposits, payroll, credit decisions and flow of materials will be carried out by a TPS system. A TPS is specified to a single functional area of business, and are transaction oriented. TPS's manage these business activities, and are usually very important to the operation of a business. The biggest advantage of a TPS is that it replaces repetitive tasks, cutting down the number of required workers, time management and therefore costs.
DDS is short for Decision Support Systems and is a computer based information system. A DDS's main function is support the business and assist management in decision making. A DDS does this displaying current and accurate data on many facets of the business. DSS’s aid management, operations, and planning levels of an organisation. DSS will usually be one of the three models: Sensitivity Analysis, What-if analysis, and Goal-Seeking analysis (these will be discussed in the following question).

Sensitivity Analysis: this model will study the impact the change in one or more parts of the model will have on other parts of the model. This is done through changing the value of one variable repeatedly and then observing the resulting changes in the other variables in the model.
What if analysis: This model will check the impact a change in an assumption will have on the proposed solution. Users will repeat the analysis till the effects of various situations are understood. This can be performed across multiple work sheets.
Goal-seeking analysis: This model will let the user know the necessary inputs needed to achieve a given goal. This is achieved by setting target value (the desired goal) for a variable and then is repeatedly changes until desired goal is achieved.

Business process improvement as stated in the above question is a vital part of any successful business, without improvements a business will fail to stay competitive in the current market. A organisation must understand and measure the current process and ensure they are always making improvements on towards it.
Reengineering: When the current process that is in place is outdated or fails to work anymore, the organisation redesigns the process to make it more effective for the business. The below figure a basic re-engineering model.
BPM is short for Business process management. What BPM does is integrates all business's processes in the organisation to make them more efficient. It can be used to create a system which combines all of the business processes or identify a singular problem. BPM's must accurately aid the business as it can change systems which were previously successful and lead larger business problems. There is strong link between accurate implementation of BPM and a successful business. Below is an example of how BPM can help businesses become more effective.
