How to implement Impact assessment for a change similar to Risks?

[rathikaramamurt]

Hi Experts,

I need to implement Impact assessment with set of questions/scores same like it is existing for Risk Assessment in the change form.

I have a list of questions and scores provided separately for both Risk as well as Impact, and can see that currently Risk assessment is already implemented, which also calculates Impact with it for each change by default.

I need to perform this action separately for both Risk & Impact. I have gone through few links Using Change Risk Assessment - ServiceNow Wiki which explains the concept clearly, for this.

However, there are links(UI actions) mentioned in this page like "Fill out Risk Assessment" and "Execute Risk Calculation". The 1st UI action, contains set of question only for Risks which calculates based on scores. Similarly I need to implement this for Impact as well like adding new UI actions only for Impact something like this--> "Fill out Impact Assessment" and "Execute Impact Calculation". I know I can copy paste same code for Impact as well, but need to know some additional background scripts running behind this, i.e., BRs and Script includes, also System properties. How these are inter related.

Could any one please guide me on this?

And 2 Script includes as below:

1. CreateImpactAssessment

script:

var CreateImpactAssessment = Class.create();

CreateImpactAssessment.prototype = Object.extendsObject(AbstractAjaxProcessor,{

//   initialize : function() {

//   },

  checkImpactAssessment: function() {

    var id = this.getParameter('sysparm_id');

    var tabClass = this.getParameter('sysparm_class');

    var assessmentID = '';

    var match = false;

    //fetch the change record

    var gr2 = new GlideRecord(tabClass);

    gr2.get(id);

    //see if an assessment already exists for this current change

    var tai = new GlideRecord('task_assessment');

    tai.addQuery('task', gr2.sys_id);

    tai.query();

    //look for matching assessment to attach //attaches the assessment to this current change based on matching assessment conditions

    var aci = new GlideRecord('assessment_conditions');

    aci.addQuery('table', tabClass);

    aci.addActiveQuery();

    aci.orderBy('order');

    aci.query();

    var retTAImpact = 'No Condition';

    while (aci.next()) {

          var filter = GlideFilter;

          match = filter.checkRecord(gr2, aci.condition);  

    //if condition matches, sets related task assessment to this current change

          if (match){

              retTAImpact = this._setAssessment(gr2, aci, tai);

              break; //match found so use this one

          }

    }

    //if condition not matches, deletes related task assessment

    if (retTAImpact == 'No Condition' && tai.next()){

        tai.deleteRecord();

    }

    return retTAImpact;

  },

  /**

  * Prevent public access to this processor

  */

  isPublic: function() {

  return false;

  },

//look for existing assessment against the task - there should be only one!

//If a task_assessment exists and the assessment to take has changed then delete the existing and create a new one

//if no task_assessment exists then create a new one

  _setAssessment: function(task, aci, tai) {

      var reti = '';

      if (tai.next()){

          // Existing assessment instance exists and is of the same type

          if (tai.assessment == aci.assessment){

              reti = tai.sys_id + ',' + tai.assessment.name;

          }

          // Existing assessment instance exists and is different so delete and associate correct one

          else{

              tai.deleteRecord();

              reti = this._create_task_assessment(tai, task.sys_id, aci);

          }

      }

      else{

  },

Thanks Rathika,

I actually implemented it this noon using the ui actions and the script includes which are used for the change management module risk assessment.

Hi @yogesh15dd , @rathikaramamurt , I have a requirement to create new pop up form "BCA exception questionnaire" which is same like Risk assessment , I tried to implement by using the ui actions and the script includes which are used for the change management module risk assessment , But it is not working for me while try to click on the link there is no pop up form appeared. could you please guide me on that.

Thank you.
