How do you like to be rewarded by your company, when you have done an achievement? كيف تحب أن تكافأ من مديرك/شركتك عندما تقوم بإنجاز جيد في عملك؟

Definitely it is appreciation.It will increase not only the self confidence but also the self respect.Employees will feel proud of their self when get appreciation from the manger side.

Its up to each one personality..
then depends on the achievement...
But i consider most of people will consider financial side as a reward for their achievements, or a promotion (that will involve for sure a salary raise) to keep motivate him/her exceed the limits, professionally speaking...

I guess all of the above required after long harsh working months, specially traveling to Georgia and loosens up the tension.

Rewards typically serve as reinforcers. A reward can be defined as reinforcer only if its delivery increases the probability of a behavior. by my hosesty i want to get rewards. 

I believe a company should have an annual reward policy.
I wouldn't mind a pat on my back for an assignment well done at that time and consideration for rewarding bonus and salary increment towards the end of the year if my achievement continues towards the profitability of the company.

طبيعة عملى منذ ار من15 عام كمدير ادارة سواء حسابات او مراجعة ( تدقيق ) او مالية جعلتنى كمسئول عن فريق افضل لى و لعملى الخيار الاخير " Titled the "Employee of the month" او - Praised among your colleagues وذلك لخلق جو تنافسى لتنشيط عمل الفريق و بالتالى الاستفادة تكون اعمق تأثيرا على العمل ككل و ذلك اكيد سيحرك الجوانب المالية على المدى البعيد فإن وجد المادى بالفريق سيستفاد اجلا و اظن الكل يفكر بالمادة على الاقل نظرا لوجود فكر ترشيد الانفاق برؤوس اغلب مسئولى الادارة المالية و ارتفاع الاسعار ذلك جعل هناك تعطش مادى اكثر من المعنوى لكنى اعتبر ان الحافز المعنوى اعمق فى تاثيره على العمل فى فريق العمل

An incentive bonus will be good, but I will settle for a simple thank you.

Truly, appreciation is one thing which motivates every employee.
Employee recognition is crucial for employee retention.
If an employee works hard, and his outcome is effective for the organization - definitely he should be appraised.
Appraisal should be in different manners:1 He/she should be appreciated based on his work2 The result of his work must be shown in terms of bonus / incentive towards month end3 Finally, based on his performance appraisal, the employee must be provided a promotion / or a raise

increase pay and bonus

Your gift or gesture should be relevant to your team member's effort.
For example, if someone comes in early for a week to make sure a project is completed on time, then a gift certificate for a great breakfast would be a good fit.
If, however, the person just saved the company from a mistake that would have cost millions, then something more significant is needed! chances are high that your team isn't looking for a bonus check or pay raise to feel appreciated.
Often, smaller gestures go further and end up costing you less in the long run.
some creative ideas to consider for showing appreciation to your team:1.Offer flexible scheduling – not everyone needs, or wants, to be in the office at8:00 a.m.
Or, you could offer telecommuting days.2.Send handwritten thank-you notes when someone goes above and beyond the requirements of the job.3.Create "free day" coupons that a worker could use for a free day off – no questions asked – without using vacation or sick time.4.Take your team out to lunch – and then, as a last-minute surprise, give them the rest of the day off.5.Give out "lazy Monday" coupons to allow a team member one "free" Monday morning off.6.If you e-mail a team member to say thank you, consider copying that message to your boss.

Each employee has his/her own unique set of drivers at any given point in time.
It could be , as examples, finance, recognition, or the desire to make a difference..
and so on. 
A financial driver may warrent incentives or pay increases, a recognition driver may require praise or tangible appreciation notes whilst the desire to make a difference driver may need to see how induvidual contributions have shaped an organisation's growth, performance and productivity.
Additionally, recognising the induvidual's driver is a good management tactic to reward and retain high performing employees.
