  • Business Impact Analysis
  • Preventative Measures
  • Recovery Strategies
  • Insurance
  • Recovery and Restoration
  • Implementing Strategies
  • Testing, Revising, and Maintaining

Business Continuity and Disaster Recovery
Overview (1)
  • Why Business Continuity Planning (BCP) and
    Disaster Recovery
  • Planning (DRP) is important?
  • Every year, thousands of businesses are affected
    by floods, fires, tornadoes, terrorist attacks,
    and vandalism in one area or another.
  • Most organizations have tangible resources,
    intellectual property, employees, computers,
    communications links, facilities, and facility
    services.
  • If any one of these resources is damaged or
    inaccessible for one reason or another, the
    company can be crippled.
  • The companies that survive these traumas are the
    ones that thought ahead, planned for the worst,
    estimated the possible damages that could occur,
    and put the necessary controls in place to
    protect themselves.

3
Overview (2) DRP vs. BCP
  • The goal of disaster recovery minimize the
    effects of a disaster and take the necessary
    steps to ensure that the resources, personnel,
    and business processes are able to resume
    operation in a timely manner.
  • DRP
  • deal with the disaster and its ramifications
    right after the disaster hits
  • is carried out when everything is still in
    emergency mode
  • BCP
  • providing methods and procedures for dealing with
    longer-term outages and disasters.
  • takes a broader approach to the problem. This
    includes getting critical systems to another
    environment while repair of the original
    facilities is taking place, getting the right
    people to the right places, and performing
    business in a different mode until regular
    conditions are back in place.

Overview (3) BCP in Overall Security Program
  • Every company should have security policies,
    procedures, standards, and guidelines. they
    provide the framework of a security program for
    an organization.
  • Business continuity should be a part of the
    security program and business decisions, as
    opposed to being an entity that stands off in a
    corner by itself.

5
Overview (4) Management Role in BCP
  • First of all, we need to identify critical
    functions and critical resources in an
    organization
  • These should be protected in a BCP
  • Who should involved in this task? Why?
  • The most critical part of establishing and
    maintaining a current continuity plan is
    management support.
  • It is critical that management understands what
    the real threats are to the company, the
    consequences of those threats, and the potential
    loss values for each threat.
  • Executives may be held responsible and liable
    under various laws and regulations. They could be
    sued by stockholders and customers if
  • The cost / benefit issues

6
Overview (5) Who will build BCP?
  • A business continuity coordinator needs to be
    identified.
  • This will be the leader for the BCP team and will
    oversee the development, implementation, and
    testing of the continuity and disaster recovery
    plans.
  • A BCP committee needs to be put together.
  • The team must be comprised of people who are
    familiar with the different departments within
    the company,

7
Overview (6) Best Practices of BCP
  • Although there is not a specific scientific
    equation that must be followed to create
    continuity plans, there are best practices that
    have proven themselves over time.
  • The National Institute of Standards and
    Technology (NIST) organization is responsible for
    developing these best practices and documenting
    them
  • Special Publication 800-34, Continuity Planning
    Guide for Information Technology Systems,
    (http//csrc.nist.gov/publications/nistpubs/800-34
    /sp800-34.pdf)

  • Business Continuity and Disaster Recovery
    Overview
  • Business Impact Analysis

  • Recovery and Restoration
  • Implementing Strategies
  • Testing, Revising, and Maintaining

10
Business Impact Analysis (1)
  • Business impact analysis (BIA) is a functional
    analysis
  • BCP committee collects data through interviews
    and documentary sources documents business
    functions, activities, and transactions develops
    a hierarchy of business functions and finally
    applies a classification scheme to indicate each
    individual functions criticality level.
  • BCP committee must identify the threats and map
    them to the following characteristics
  • Maximum tolerable downtime (MTD)
  • Operational disruption and productivity
  • Financial considerations
  • Regulatory responsibilities
  • Reputation

11
Business Impact Analysis (2)
  • BIA steps
  • Select individuals to interview for data
    gathering.
  • Create data-gathering techniques.
  • Identify the companys critical business
    functions.
  • Identify the resources that these functions
    depend upon.
  • Calculate how long these functions can survive
    without these resources -- maximum tolerable
    downtime (MTD)
  • Identify vulnerabilities and threats to these
    functions.
  • Calculate risk for each different business
    function.
  • Document findings and report them to management.

12
Business Impact Analysis (3)Maximum tolerable
downtime (MTD)
  • The outage time that can be endured by a company
    is referred to as the maximum tolerable downtime
    (MTD).
  • Some MTD estimates that may be used within an
    organization
  • Nonessential 30 days
  • Normal 7 days
  • Important 72 hours
  • Urgent 24 hours
  • Critical Minutes to hours
  • Each business function and asset should be placed
    in one of these categories. ? to determine what
    backup solutions are necessary to ensure the
    availability of these resources.
  • E.g. MTD of a T1 communication line is three
    hours and cost 130,000
  • MTD of a sever is ten days and cost 250

13
Business Impact Analysis (4)Risk Analysis
  • Threats can be manmade, natural, or technical
  • Manmade threats an arsonist, a terrorist, or a
    simple mistake that can have serious outcomes.
  • Natural threats tornadoes, floods, hurricanes,
    or earthquakes.
  • Technical threats data corruption, loss of
    power, device failure, or loss of a data
    communications line.
  • Steps of risk analysis
  • To identify all possible threats and estimate the
    probability of them happening.
  • To assign a value to the assets that could be
    affected by each threat.
  • The value an asset include the amount of money
    paid for it, the assets role to the company, and
    liability issues.
  • Risk the likehood of a negative event happening
    the impact of such an event happening

14
Business Impact Analysis (5)Quantitative vs.
Qualitative
  • In BIA, information should be stated in
    quantitative terms, not in subjective,
    qualitative terms.
  • e.g., If a tornado were to hit, the result would
    be really bad.
  • If a tornado were to hit and affect 65 percent
    of the facility, the company could be at risk of
    losing computing capabilities for up to 72 hours,
    power supply for up to 24 hours, and a full stop
    of operations for 76 hours, which would equate to
    a loss of 125,000 each day.

15
Business Impact Analysis (6)Interdependencies in
BIA
  • A company comprises many types of equipment,
    people, tasks, departments, communications
    mechanisms, and interfaces to the outer world.
  • The biggest challenge of continuity planning is
    understanding all of these intricacies and their
    interrelationships.

16
Example of Dependency Chart
17
Business Impact Analysis (7)Software tools
  • There are several software tools available for
    developing a BCP that simplify the process.
  • Business Continuity Plan Generator
  • comprises two major elements a template and a
    guide.
  • Disaster Recovery Toolkit is designed to help
    you review the full array of business continuity
    and disaster recovery issues. It comprises
  • A contingency audit questionnaire
  • A Business Impact Analysis questionnaire.
  • An audit questionnaire for your disaster recovery
    or business continuity plan (if indeed you have
    one)
  • A checklist, action list and framework for
    disaster recovery

19
Preventative Measures (1)
  • To reduce negative impact and mitigate these
    risks by implementing preventative measures.
  • instead of just waiting for a disaster to hit to
    see how the company holds up, countermeasures
    should be integrated to better fortify the
    company from the impacts that were recognized.
  • Appropriate and cost-effective, preventative
    methods and proactive measures are more
    preferable than reactionary methods.

20
Preventative Measures (2)
  • Preventative Measures include
  • Fortification of the facility in its construction
    materials
  • Redundant servers and communications links
  • Power lines coming in through different
    transformers
  • Redundant vendor support
  • Purchasing of insurance
  • Purchasing of UPS and generators
  • Data backup technologies
  • Media protection safeguards
  • Increased inventory of critical equipment
  • Fire detection and suppression systems

22
Recovery Strategy (1)
  • In the recovery strategy stage, the team try to
    figure out what the company needs to do to
    actually recover the items that it has identified
    to be so important to the organization.
  • discover the most cost-effective recovery
    mechanisms that need to be implemented to address
    the threats that were identified in the BIA
    stage.
  • Preventative mechanisms
  • Are put into place to try to reduce the
    possibility of the company experiencing a
    disaster
  • If a disaster does hit, to lessen the amount of
    damage that will take place.
  • Recovery strategies are a set of predefined
    activities that will be implemented and carried
    out in response to a disaster..
  • Such as establishing alternate sites for
    facilities, implementing emergency response
    procedures, etc.

23
Recovery Strategy (2)
  • In BIA phase, the team has figured out these
    types of timelines for the individual business
    functions, operations, and resources. (MTD)
  • In develop recovery strategy phase, the team
    needs to identify the recovery mechanisms and
    strategies that must be implemented to make sure
    that everything is up and running within the
    timelines that it has calculated.
  • Business process recovery
  • Facility recovery
  • Supply and technology recovery
  • User environment recovery
  • Data recovery

24
Business Process Recovery
  • A business process is a set of interrelated steps
    linked through specific decision activities to
    accomplish a specific task.
  • The processes should encapsulate the knowledge of
    services, resources, and operations provided by a
    company.
  • E.g., when a customer requests to buy a car via
    an organizations e-commerce site, a set of steps
    must be followed.
  • The BCP team needs to understand these different
    steps of the companys most critical steps.
  • The data is usually presented as a workflow
    document

25
Example of Workflow
26
Facility Recovery (1)
  • Three main categories of disruptions
  • nondisaster, disaster, and catastrophe
  • A nondisaster is a disruption in service as a
    result of a device malfunction or failure.
  • Replacing a device or restoring files from onsite
    backups
  • The team needs to identify the critical equipment
    and estimate the mean time between failure (MTBF)
    and mean time to repair (MTTR)
  • MTBF is the estimated lifetime of a piece of
    equipment
  • MTTR is an estimate of how long it will take to
    fix a piece of equipment

27
Facility Recovery (2)
  • A disaster is an event that causes the entire
    facility to be unusable for a day or longer.
  • Usually requires the use of an alternate
    processing facility
  • A catastrophe is a major disruption that destroys
    the facility altogether.
  • Requires both a short-term solution (an offsite
    facility) and a long-term solution (rebuilding
    the original facility)

28
Facility Recovery (3)
  • Companies can choose from three main types of
    leased or rented offsite facilities Hot site,
    Warm site, Cold site
  • Hot site a facility that is leased or rented and
    is fully configured and ready to operate within a
    few hours.
  • The only missing resources from a hot site are
    usually the data (will be retrieved from a backup
    site), and the people who will be processing the
    data.
  • Are a good choice for a company that needs to
    ensure that a site will be available for it as
    soon as possible.
  • the annual testing guarantee its operating state
  • A hot site can support a short- or long-term
    outage
  • the most expensive choice among three offsites

29
Facility Recovery (4)
  • Warm site a leased or rented facility that is
    usually partially configured with some equipment,
    but not the actual computers.
  • A warm site a hot site - the expensive
    equipments
  • Less expensive than a hot site
  • Can be up and running within a reasonably
    acceptable time period.
  • The most widely used model
  • Drawback the annual testing is not usually
    available. Thus a company cannot be certain that
    it will in fact be able to return to an operating
    state within hours.

30
Facility Recovery (5)
  • Cold site A leased or rented facility that
    supplies the basic environment
  • Electrical wiring, air conditioning, plumbing,
    and flooring, but none of the equipment or
    additional services.
  • It may take weeks to get the site activated and
    ready for work.
  • the least expensive option
  • Comparison among three offsite options P712

31
Facility Recovery (6)
  • Alternatives to offsite facility
  • Reciprocal agreement
  • Redundant sites
  • Reciprocal agreement, also referred to as mutual
    aid, with another company.
  • This means that company A agrees to allow company
    B to use its facilities if company B is hit by a
    disaster, and vice versa.
  • A cheaper way to go than the other offsite
    choices, but it is not always the best choice.

32
Facility Recovery (7)
  • Redundant sites one site is equipped and
    configured exactly like the primary site, which
    serves as a redundant environment.
  • Primary site, backup site, and tertiary site.
  • These sites are owned by the company and are
    mirrors of the original production environment.
  • The most expensive backup facility options,
    because a full environment must be maintained.
  • Other facility-backup options
  • Rolling hot site (mobile hot site)
  • multiple processing centers

33
Facility Recovery (8)
  • Hot site vs. redundant site
  • A hot site are provided by service bureaus, is a
    subscription service.
  • A redundant site is a site owned and maintained
    by the company. The company does not pay anyone
    else for the site.

34
Supply and Technology Recovery (1)
  • BCP team needs to dig down into some more
    granular
  • items, such as backup solutions for the
    following
  • Network and computer equipment
  • Voice and data communications resources
  • Human resources
  • Transportation of equipment and personnel
  • Environment issues (HVAC)
  • Data and personnel security issues
  • Supplies (paper, forms, cabling, and so on)
  • Documentation

35
Supply and Technology Recovery (2)
  • It is not easy to fully understand the
    organizations current
  • technical environment, because
  • The network was most likely established years ago
    and has kept growing
  • Over years, a number of technology refreshes have
    taken place
  • Employee turnover the individuals who are
    maintaining the environment now are not the same
    people who built it years ago.

36
Supply and Technology Recovery (3)hardware backup
  • The team has identified the equipment that is
    required to keep the critical functions up and
    running.
  • Issue 1 Using images vs. building from scratch
  • Using images is time-saving,
  • unless the team finds out that the replacement
    equipment is a newer version and thus the images
    cannot be used.
  • The BCP team should plan for the recovery team to
    use the companys current images, but also have a
    manual process of how to build each critical
    system from scratch with the necessary
    configurations.

37
Supply and Technology Recovery (4)hardware backup
  • Issue 2 Depending on SLA vs. redundant system
  • MTD indicates how long the company can be without
    a specific device.
  • Knowing the parameters of the SLA
  • The BCP team needs to make a decision between
    depending upon the vendor or purchasing redundant
    systems and storing them as backups
  • Issue 3 legacy system vs. COTS product
  • The team should identify legacy devices and
    understand the risk that the organization is
    under if replacements are unavailable.
  • This type of finding has caused many companies to
    move from legacy systems to commercial off the
    shelf (COTS) products to ensure that replacement
    is possible.

38
Supply and Technology Recovery (5) Software Backup
  • The BCP team should make sure to have an
    inventory of the necessary software that is
    required for mission-critical functions and have
    backup copies at an offsite facility.
  • At least two copies of the companys operating
    system software and critical applications.
  • One copy should be stored onsite and the other
    copy should be stored at a secure offsite
    location.
  • These copies should be tested periodically and
    re-created when new versions are rolled out.

39
Supply and Technology Recovery (6) Software Backup
  • Customized software usually comes without source
    code
  • What if this software vendor goes out of business
    because of a disaster or bankruptcy?
  • A company will require a new vendor to maintain
    and update this customized software thus, the
    new vendor will need access to the source code.
  • Software escrow means that a third party holds
    the source code, backups of the compiled code,
    manuals, and other supporting materials.
  • This contract usually states that the customer
    can have access to the source code only if and
    when the vendor goes out of business, is unable
    to carry out stated responsibilities, or is in
    breach of the original contract.

40
Supply and Technology Recovery (7) Documentation
  • Without documentation, when a disaster hits, no
    one will
  • know how to put critical function back together
    again.
  • The documentation needs to include
  • information on how to install images, configure
    operating systems and servers, and properly
    install utilities and proprietary software.
  • A calling tree, which outlines who should be
    contacted, in what order, and who is responsible
    for doing the calling.
  • Multiple copies One copy may be at the primary
    location. Typically, a copy is stored at the BCP
    coordinators home and a copy is stored at the
    offsite facility. This reduces the risk of not
    having access to the plans when needed.

41
Supply and Technology Recovery (8) Human Resources
  • Human resources is a critical component to any
    recovery
  • and continuity process
  • Issue 1 If a large disaster takes place, will
    employees be more worried about your company or
    their families?
  • Issue 2 The BCP team may need to look at how it
    will be able to replace employees quickly through
    a temporary agency or a headhunter.
  • Issue 3 executive succession planning
  • If someone in a senior executive position
    retires, leaves the company, or is killed, the
    organization has predetermined steps to carry out
    to protect the company.
  • Deputies are ready to take over the necessary
    tasks
  • A policy indicating that to protect the United
    States, its top leaders cannot be under the same
    risk at the same time.

42
Supply and Technology Recovery (9) End-User
Environment
  • The end users must be provided a functioning
    environment
  • as soon as possible after a disaster hits.
  • How the end users will be notified of the
    disaster and who will tell them where to go and
    when.
  • A tree structure of managers can be developed
  • After a disaster, only a skeleton crew is put
    back to work.
  • The BCP committee identified the most critical
    functions of the company during the analysis
    stage, and the employees who carry out those
    functions must be put back to work first.
  • The BCP team needs to identify user requirements
  • stand-alone PCs, networked systems
  • The BCP team needs to identify how current
    automated tasks can be carried out manually if
    that becomes necessary.

43
Supply and Technology Recovery (10) Data Backup
  • The BCP teams responsibility is to provide
    solutions to protect this data and identify ways
    to restore it after a disaster.
  • Data has become one of the most critical assets
    to nearly all organizations.
  • Data usually changes more often than hardware and
    software, so these backup procedures must happen
    on a continual basis.
  • The data backups can be full, differential, or
    incremental backups and are usually used in some
    type of combination.
  • Most companies choose to combine a full backup
    with a differential OR incremental backup.

44
Supply and Technology Recovery (11) Data Backup
  • Full Process
  • All data is backed up and saved to some type of
    storage media.
  • The archive bit is clear
  • the restoration process is just one step, but the
    backup and restore processes could take a long
    time.
  • Differential Process
  • Backs up the files that have been modified since
    the last full backup.
  • Does not change the archive bit value.
  • When the data needs to be restored, the full
    backup is laid down first and then the
    differential backup is put down on top of it.

45
Supply and Technology Recovery (12) Data Backup
  • Incremental process
  • Backs up all the files that have changed since
    the last full or incremental backup
  • The archive bit is clear
  • When the data needs to be restored, the full
    backup data is laid down and then each
    incremental backup is laid down on top of it in
    the proper order.
  • A comparison of three data backup processes is
    next

46
Supply and Technology Recovery (13) Data Backup
  • How to choose a data back up process?
  • Although using differential and incremental
    backup processes is more complex, it requires
    less resources and time.
  • A differential backup takes more time in the
    backing up phase than an incremental backup, but
    it also takes less time to restore than an
    incremental backup. Why?
  • Do NOT mix differential and incremental backups!
  • Full process differential backup
  • OR Full process incremental backup
  • A backup strategy must take into account that
    failure can take place at any step of the
    process.
  • Test is essential! ? avoid developing false sense
    of security

47
Supply and Technology Recovery (14) Data Backup
  • Several automated backup alternatives
  • Disk-shadowing, Electronic vaulting, Remote
    journaling, Hierarchical storage management
    (HSM), Storage area network (SAN), automatic tape
    vaulting.
  • Manually backing up systems and data can be time
    consuming, error prone, and costly.
  • Disk-shadowing (data-mirroring)
  • A disk-shadowing process uses two physical disks,
    and the data is written to both at the same time
    for redundancy purposes. If one disk fails, the
    other is readily available.
  • Provides online backup storage, which can either
    reduce or replace the need for periodic offline
    manual backup operations.
  • Provides transparency to the user
  • Another benefit is that it can boost read
    operation performance.
  • Is an expensive solution

48
Supply and Technology Recovery (15) Data Backup
  • Electronic vaulting makes copies of files as
    they are modified and periodically transmits them
    to an offsite backup site.
  • The transmission is carried out in batches
  • Can choose to have all files that have been
    changed sent to the backup facility every hour,
    day, week, or month.
  • How to choose a transmission period?
  • Remote journaling only includes moving the
    journal or transaction logs to the offsite
    facility, not the actual files.
  • These logs contain the deltas (changes) that have
    taken place to the individual files.
  • Takes place in real time
  • Is efficient for database recovery. Why?

49
Supply and Technology Recovery (16) Data Backup
  • hierarchical storage management (HSM) provides
  • continuous online backup functionality.
  • It combines hard disk technology with the cheaper
    and slower optical or tape jukeboxes.
  • Dynamically manages the storage and recovery of
    files, which are copied to storage media devices
    that vary in speed and cost.
  • The faster media holds the data that is accessed
    more often
  • The seldom-used files are stored on the slower
    devices, or near-line devices
  • Happens in the background without the knowledge
    of the user or any need for user intervention.

50
Supply and Technology Recovery (17) Data Backup
51
Supply and Technology Recovery (18) Data Backup
  • Storage area network (SAN) is a dedicated network
    that is separated
  • from LANs and WANs. It serves to interconnect the
    storage-related
  • resources that are connected to one or more
    servers.
  • Usually provided by using switches to create a
    switching fabric -- enables several devices to
    communicate with back-end storage devices
  • Provides redundancy and fault tolerance by not
    depending upon one specific line or connection.
  • Includes RAID systems as primary data storage
    devices, which offer data protection and fault
    tolerance.
  • Private channels or storage controllers are
    implemented so that hosts can access the storage
    devices transparently.

52
Supply and Technology Recovery (19) Data Backup
  • Automatic tape vaulting
  • The data is sent over a serial line to a backup
    tape system at the offsite facility.
  • Data can be quickly backed up and retrieved when
    necessary.
  • Reduces the manual steps in the traditional tape
    backup procedures.

54
Insurance (1)
  • Why we need to consider insurance in BCP?
  • Ans Taking on the full risk of these threats
    often is dangerous
  • The decision of whether or not to obtain
    insurance for a particular threat, and how much
    coverage to obtain when choosing to insure,
    should be based on the probability of the threat
    becoming real and the loss potential
  • Insurance coverage has its limitations
  • if the company does not practice due care, the
    insurance company may not be legally obligated to

Recovery and Restoration (1)
  • Several different teams that should be properly
    trained and available if a disaster hits.
  • Damage assessment team
  • Legal team
  • Media relations team
  • Network recovery team
  • Relocation team
  • Restoration team
  • Salvage team
  • Security team
  • Telecommunications team
  • The BCP must outline the specific teams, their
    responsibilities, and notification procedures.

58
Recovery and Restoration (2)
  • The damage assessment is completed
  • ? the BCP is activated
  • ? various teams are deployed, which signals the
    companys entry into the recovery phase.
  • The recovery process needs to get the company up
    and running as soon as possible.
  • When it is time for the company to move back into
    its original site or a new site, the company is
    ready to enter into the reconstitution phase.

60
Implementing Strategies (1)
  • Once the strategies have been decided upon, they
    need to
  • be documented and put into place by the BCP team.
  • The plan should address in detail all of the
    topics that we have covered.
  • The plan also needs to integrate a degree of
    flexibility
  • No one knows exactly what type of disaster will
    take place nor its effects.
  • Some organizations develop individual plans for
    specific tasks and goals.
  • The BCP team can choose to integrate many of
    these components into the BCP

63
Testing, Revising, and Maintaining (1)
  • The BCP should be tested / exercised regularly
  • Because environments continually change
  • Each time the plan is exercised / tested,
    improvements and efficiencies are generally
    uncovered
  • The exercise should have a predetermined scenario
    that the company may indeed be faced with one
    day.
  • There are a few different types of tests
  • Checklist Test
  • Structured Walk-Through Test
  • Simulation Test
  • Parallel Test
  • Full-Interruption Test

64
Testing, Revising, and Maintaining (2)
  • Checklist Test copies of the BCP are distributed
    to the different departments and functional areas
    for review.
  • Structured Walk-Through Test representatives
    from each department or functional area come
    together to go over the plan to ensure its
    accuracy.
  • walks through different scenarios of the plan
    from beginning to end to make sure nothing was
    left out.
  • Simulation Test all employees who participate in
    operational and support functions, or their
    representatives, come together to practice
    executing the disaster recovery plan based on a
    specific scenario.
  • Parallel Test Some systems are moved to the
    alternate site and processing takes place.

65
Testing, Revising, and Maintaining (3)
  • Full-Interruption Test
  • The original site is actually shut down and
    processing takes place at the alternate site.
  • The recovery team fulfills its obligations in
    preparing the systems and environment for the
    alternate site.
  • All processing is done only on devices at the
    alternate offsite facility.
  • This is a full-blown drill that takes a lot of
    planning and coordination, but it can reveal many
    holes in the plan that need to be fixed before an
    actual disaster hits.
  • Should be performed only after all other types of
    tests have been successful
  • The most risky and can impact the business in
    very serious and devastating ways if not managed
    properly

66
Testing, Revising, and Maintaining (4)
  • Unfortunately, the BCP can become quickly out of
    date
  • An out of date BCP may provide a company with a
    false sense of security
  • Organizations can keep the plan updated by taking
    the following actions
  • Make business continuity a part of every business
    decision.
  • Insert the maintenance responsibilities into job
    descriptions.
  • Include maintenance in personnel evaluations.
  • Perform internal audits that include disaster
    recovery and continuity documentation and
    procedures.
  • Perform regular drills that use the plan.
  • Integrate the BCP into the current change
    management process.
