The correct answer is D. All of the above.
Your job description, the size of the organization, and your relevant experience all affect the extent to which you are involved with the system development life cycle in your company.
Your job description will determine your specific responsibilities and tasks. If your job description includes tasks related to system development, then you will be more involved in the system development life cycle.
The size of the organization will also affect your involvement in the system development life cycle. In a small organization, you may be involved in all aspects of the system development life cycle, from planning and analysis to implementation and maintenance. In a large organization, you may be more specialized and only involved in a specific phase of the system development life cycle.
Your relevant experience will also affect your involvement in the system development life cycle. If you have experience in system development, you will be more likely to be involved in the system development life cycle. If you do not have experience in system development, you may be less involved in the system development life cycle.
In addition to the factors mentioned above, your involvement in the system development life cycle may also be affected by your level of education, your training, your skills, and your interests.
