Answer c:
There are many physical internal control weaknesses are present in the given system. Some of them are described here.

* Physical count of inventory * wasteful and inefficient use of resources * poor management decisions * unintentional errors recording or processing data * accidental loss or destruction of records * loss of assets through employee carelessness * lack of compliance by employees with management policies
The above are all the some weaknesses which are not present. If management wants to overcome these weaknesses in short time then first change the policy and make new strategy and immediately implement on the business to get the good results in less time. If the organization keeps going on the old policies and with the weaknesses then it will lead a failure or may be shutdown of operations in future.
Internal control means different things to different people. This causes confusion among businesspeople, legislators, regulators and others. Resulting miscommunication and different expectations cause problems within an enterprise. Problems are compounded when the term, if not clearly defined, is written into law, regulation or rule.
This report deals with the needs and expectations of management and others. It defines and describes internal control to:
1. Establish a common definition serving the needs of different parties.
2. Provide a standard against which business and other entities--large or small, in the public or private sector, for profit or not can assess their control systems and determine how to improve them.
Internal control is broadly defined as a process, affected by an entity's board of directors, management and other personnel, designed to provide reasonable assurance regarding the achievement of objectives in the following categories:
1. Effectiveness and efficiency of operations.
2. Reliability of financial reporting.
3. Compliance with applicable laws and regulations.
The first category addresses an entity's basic business objectives, including performance and profitability goals and safeguarding of resources. The second relates to the preparation of reliable published financial statements, including interim and condensed financial statements and selected financial data derived from such statements, such as earnings releases, reported publicly. The third deals with complying with those laws and regulations to which the entity is subject. These distinct but overlapping categories address different needs and allow a directed focus to meet the separate needs.

Answer d:
Now a day’s I.T plays a vital role in the life of business. For running the operations information technology plays an essential role in this. Without I.T business can’t be make stronger because every operation of business needs and use of information technology. The capacity of IT contributes to the growth of enterprises. Several studies of international medium-sized companies show that the capacity of IT has a close correlation with the growth of the cost-effectiveness of the organizations. Data obtained from these studies indicate that IT accelerates the growth of businesses because it provides them with scalability, the ability to successfully manage the increase in the complexity of the organization and its processes and business model. Companies with business processes scalability are better placed to overcome obstacles to growth, differentiate themselves from the competition and quickly seize the business opportunities that arise. In summary, the use of IT is relevant and is an essential ingredient for the success of companies’ long term. IT is not simply a component whose influence on the prosperity of the company is nothing to be lowered. IT promotes the growth of organizations.

In business and accounting, information technology controls (or IT controls) are specific activities performed by persons or systems designed to ensure that business objectives are met. They are a subset of an enterprise's internal control. IT control objectives relate to the confidentiality, integrity, and availability of data and the overall management of the IT function of the business enterprise. IT controls are often described in two categories: IT general controls (ITGC) and IT application controls. ITGC include controls over the Information Technology (IT) environment, computer operations, access to programs and data, program development and program changes. IT application controls refer to transaction processing controls, sometimes called "input-processing output" controls. Information technology controls have been given increased prominence in corporations listed in the United States by the Sarbanes Oxley Act. The COBIT Framework (Control Objectives for Information Technology) is a widely used framework promulgated by the IT Governance Institute, which defines a variety of ITGC and application control objectives and recommended evaluation approaches. IT departments in organizations are often led by a Chief Information Officer (CIO), who is responsible for ensuring effective information technology controls are utilized.
IT application or program controls are fully automated (i.e., performed automatically by the systems) designed to ensure the complete and accurate processing of data, from input through output. These controls vary based on the business purpose of the specific application. These controls may also help ensure the privacy and security of data transmitted between applications. Categories of IT application controls may include:

Completeness checks - controls that ensure all records were processed from initiation to completion.
Validity checks - controls that ensure only valid data is input or processed.
Identification - controls that ensure all users are uniquely and irrefutably identified.
Authentication - controls that provide an authentication mechanism in the application system.
Authorization - controls that ensure only approved business users have access to the application system.
Input controls - controls that ensure data integrity fed from upstream sources into the application system.
Forensic controls - control that ensure data is scientifically correct and mathematically correct based on inputs and outputs

The organization's Chief Information Officer (CIO) or Chief Information Security Officer (CISO) is typically responsible for the security, accuracy and the reliability of the systems that manage and report the company's data, including financial data. Financial accounting and enterprise resource planning systems are integrated in the initiating, authorizing, processing, and reporting of financial data and may be involved in Sarbanes-Oxley compliance; to the extent they mitigate specific financial risks.
So, these internal controls systems are the very important for the business organization. By which the organization can increase its productivity in time and growth will be increases shortly and in a better way.
