• Bring your own device (BYOD) (also called bring your own technology (BYOT), bring your own phone (BYOP), and bring your own PC (BYOPC)) means the policy of permitting employees to bring personally owned mobile devices (laptops, tablets, and smart phones) to their workplace, and use those devices to access privileged company information and applications.The term is also used to describe the same practice applied to students using personally owned devices in education settings

• What is Bring your own device (BYOD)?

Bring your own device (BYOD) is an IT policy where employees are allowed or encouraged to use their personal mobile devices—and, increasingly, notebook PCs—to access enterprise data and systems. There are four basic options, which allow:

    Unlimited access for personal devices.
    Access only to non-sensitive systems and data.
    Access, but with IT control over personal devices, apps and stored data.
    Access, while preventing local storage of data on personal devices.

• What is CapEx and OpEx?

CapEx refers to a Capital expenditure while OpEx refers to an Operational expenditure. Capital expenditure is incurred when a business acquires assets that could be beneficial beyond the current tax year. For instance, it might buy brand new equipment or buildings. Also, it could upgrade an existing asset to boost its value beyond the current tax year. CapEx is also known as a Capital expense.
Operational expenditure consists of those expenses that a business incurs to run smoothly every single day. They are the costs that a business incurs while in the process of turning its inventory into an end product. Hence, depreciation of fixed assets that are used in the production process is considered OpEx expenditure. OpEx is also known as an operating expenditure, revenue expenditure or an operating expense.
How CapEx and OpEx are Treated in Accounting
CapEx – Capital expenditures are not fully deducted in the accounting period they were incurred. In other words, they are not fully subtracted from the revenue when computing the profits or losses a business has made. However, intangible assets are amortized over their lifespan while the tangible ones are depreciated over their life cycle. All monies spent to get new inventory, including machinery or intellectual property, are grouped under CapEx spendings.

OpEx – Operating expenses are fully deducted in the accounting period they were incurred. All funds spent when converting inventory into throughput falls under OpEx. This includes employee wages, repair and maintenance of equipment, rental fees, and utility bills and so on. If a business invests in real estate, these spending is approved as CapEx budget and the expense is grouped under CapEx. However, all the costs incurred when managing such an income generating building falls under OpEx.

IT Spending – CapEx or OpEx?
Traditionally technology investments most often were considered for capital expenditures over OpEx, because CFOs could take advantage of amortization these expenses over an extended period of time. Nowadays, more and more companies switch IT investment from CapEx to OpEx and they have a reasonable argument for this switch – moving company IT infrastructure to the cloud. Once this moving happens, additional CapEx benefits fall as far as the company no longer need static investments for the hardware, software and resources.

• A COTS (commercial off-the-shelf) product is one that is used "as-is." COTS products are designed to be easily installed and to interoperate with existing system components. Almost all software bought by the average computer user fits into the COTS category: operating systems, office product suites, word processing, and e-mail programs are among the myriad examples. One of the major advantages of COTS software, which is mass-produced, is its relatively low cost.

• A COTS product is usually a computer hardware or software product tailored for specific uses and made available to the general public. Such products are designed to be readily available and user friendly. A typical example of a COTS product is Microsoft Office or antivirus software. A COTS product is generally any product available off-the-shelf and not requiring custom development before installation

• proof of concept (POC)

When a company is asked to invest in a another company or project, usually a proof of concept is required to demonstrate that the proposal is fiscally sound.
For example, a company interested in developing a new suite of software would look at market demand, feasibility of the project, projected cost, and other factors.
