Can the Annual Operating Plan of the company be modified as the year progresses?

yes I think it should be , if there is anything wrong,  or  an inexpected event  happenend , then it would  really not  be  wise to stick to the initial plan.

Sure. Something that was planned not always be achieved or feasible, the plans need to be monitored and how their implementation, if necessary, to get something better, modification, repair, corrected ....This is advance planning and may show some unforeseen situations, the causes and the like, so there must be a deviation from the original plan.

No, I think that the operational plans are not flexible, must be accomplished under any circunstance. For this reason the operational risk plan is associated at operational plan.

Yes, to incorporate to close the loose gaps and one off material incidents, which may expose the company to higher risk need immediate change of Standard Operating plans / procedures.

Yes. The plan is built on a set of anticipated parameters. If any of these parameters behave in an unexpected manner or if an unanticipated parameter comes into play, the annual operating plan must be modefied to deal with the current or expected realities.

Yes, according to the real circumstances.

Yes it can be, rather it is normal to revise it, many of your plans and budgets depend upon the economical conditions, market requirement and demand, change of fashions and trends, change in technology as well as alterations and amendements in legislations & rulings.

Initial Annual Operating Plans is to be deal as estimate, and your estimations and actual incidents do vary.

Any plan must be flexible and plan's success is measured by the extent of flexibilityThat my point of view

i believe rigid plans fail.any plan should be flexible enough for required or needed adjustments as the medium we are working in isn't standing still.things shift and change and we must adjust to meet change dynamics.

Successful strategic plans are not static. As a practical management maneuver, strategic plans should be evaluated on an annual basis for progress toward accomplishment of goals and objectives. This annual assessment may reveal the need to make a few adjustments or accommodations. However, unless extraordinary changes in internal capacity or external operating environment have occurred, it should not be necessary to overhaul or rewrite an entire strategic plan annually. Barring an extraordinary internal or external change, major review, revision, and update should not be needed before the mandatory review and update.

When to revise the plan depends upon:

- There are significant changes in internal capacity or external operating environment; Strategies and

-  action plans are not proceeding on schedule or working as expected; Progress toward goals and

-  objectives is not being made as expected; Anticipated results are not being achieved;

-  Unexpected or undesirable consequences are being generated; or

-  Current goals and objectives are inadequate or unrealistic,

It is not easy that means having losses or failure of what should be studied before changes
