Our example laid out the KPI of completed tasks, specifically two blogs per week. This phase is focused on creating a reasonable goal for that role as it fits into the context of the company. Your understanding of the role may help with the initial goal for the KPI , but standardizing this amongst the members of your team in this role will assist in finding a number that is productive and inspiring without risking burnout.
After a couple weeks to a month of testing the KPI baseline, sit down with the members of your team to review not only their metrics, but the KPIs themselves. If all of your employees are struggling to meet the KPIs, or the ones that meet them successfully are able to do so by sacrificing quality, then you might use this as an opportunity to adjust the target more broadly.
However, using an AI writer to create content is always an option. The point of analytics is not to reduce employees to a numerical reasoning test of output, rather to give goals to strive for.
Success, whether it be first time or routine, is a reason to celebrate as a positive reinforcement towards a continued commitment of these goals. Celebrations can come in many forms big or small , but such team-facing acknowledgments help establish visible patterns by which promotions are earned transparently and through indisputable meritocracy.
Utilizing enterprise project management software such as Nifty will help you and your team start off with the meaningful basics of performance analysis software. Alternatively, you can use free tools like Google Sheets to create dashboards , but this is harder.
One way to start is perhaps the simplest KPI out there: the number of tasks assigned versus amount of tasks completed. Members of the team will be able to reference all of their assignments from their My Tasks screen to give them extreme actionability without needing to visit every project individually.
As a manager, you can track and even export reports open and completed tasks from Workloads to gauge whether or not members of your team are tackling their weekly assignments or if the volume of tasks assigned needs to be calibrated.
The lean methodology above is a great way to get a framework in place for setting and measuring expectations, but the Task Volume KPI has a notable blindspot being that two tasks might not require nearly the same amount of work. In this case, the Volume KPI belies the effort it might take for one employee to complete their four rigorous tasks when another employee has four fairly simple tasks.
To account for this, Nifty offers a resource methodology called Story Points. Optimize many-to-many dimension performance, if used.

Define aggregations to reduce the number of records that the storage engine needs to scan from disk to satisfy a query. Avoid designing an excessive number of aggregations. Excessive aggregations reduce processing performance and may reduce query performance. Enable the analysis services query log to capture user query patterns and use this query log when designing aggregations.
Define partitions to enable analysis services to query fewer data to resolve a query when it cannot be resolved from the data cache or from aggregations. Also, define the partitions to increase parallelism when resolving queries.
For optimum performance, partition data in a manner that matches common queens. A very common choice for partitions is to select an element of time such as day, month, quarter, a year or some combination of time elements in most cases, partitions should contain fewer than 20 million record size and each measure group should contain fewer than 2,00 total partitions.
Also, avoid defining partitions containing fewer than two million records. Too many partitions cause a slowdown in metadata operations, and too few partitions can result in missed opportunities for parallelism. Define a separate ROLAP partition for REAL-time ROLAP partition in its own measure group.
Remove empty tuples from your result set to reduce the time spent by the query execution engine serializing the result set.
Avoid Run-time checks in an MDX calculation that result in a slow execution path. If you use the case and If functions to perform condition checks which must be resolved many times during query resolution, you will have a slow execution path. Rewrite these queries using the SCOPE function to quickly reduce the calculation space to which on MDX calculation refers.
Use Non-Empty-Behavior where possible to enable the query execution engine to we bulk evaluation mode. However, if you use Non-Empty-Behavior incorrectly, you will return incorrect results.
Use EXISTS rather than filtering on member properties to avoid a slow execution path. Use the nonempty and exists functions to enable the query execution engine to use bulk evaluation mode.
Perform string manipulations within analysis services stored procedures using server-side ADOMD. NET rather than with string manipulation functions such as str to member and str to set.
Rather than using the lookup cube function, use multiple measure groups in the same cube wherever possible. Rewrite MDX queries containing arbitrary shapes to reduce excessive subqueries where possible. The set { Gender. male, customer.
USA , Gender. Female, Customer. Canada } is an arbitrary Set. You can frequently use the descendant's function to resolve arbitrary shapes by using a smaller number of subqueries than queries than returning the same result that is written using other functions.
Rewrite MDX queries that result in excessive perfecting where possible.
